Executive Summary
The Kiribati Aviation Investment Project (KAIP) was established to carry out the upgrade activities as identified in
the Pacific Aviation Investment Program (PAIP) funding loan from the World Bank (WB). The KAIP aims to
improve Kiribati’s airport infrastructure, meet International Civil Aviation Organisation (ICAO) standards (for
international airports), and to ensure sustainable operation of the civil aviation sector in Kiribati. This Basic
Environmental Impact Assessment (BEIA) and Environmental Management Plan (EMP) has been prepared for
the Bonriki International Airport (TRW) KAIP project components which are listed below and to meet with funding
and Kiribati legislative requirements.
- Runway pavement rehabilitation
- Perimeter security fence
- Upgraded terminal
- Upgraded navigational aids
The Ministry of Communication, Transport and Tourism Development (MCTTD) through the Civil Aviation
Directorate (CAD) manage the airport operations and are responsible for compliance with national and
international civil aviation requirements.
This BEIA and EMP looks to outline the potential environmental impacts and the measures needed to prevent,
minimise, or mitigate adverse impacts and improve environmental performance for the KAIP project components.
Overall the KAIP is a Category B project under WB environmental and social screening guidelines and requires
development of the project EMP. Category B projects have potentially limited adverse social or environmental
impacts that are few in number, site specific, largely reversible, and readily addressed through mitigation
measures. The EMP is a dynamic document to be updated if there are changes to the project scope, detailed
designs, or if further information becomes available as a result of consultation with stakeholders and the
community. The objective of the BEIA and EMP is to provide a framework for managing the airport upgrade works
in a manner that incorporates the principles of environment sustainability while minimising potential adverse
effects on the local community and the environment.
This BEIA and EMP includes information on mitigation, monitoring, capacity development and training, and
implementation costs (in accordance with WB Operational Policy 4.01 Environmental Assessment). The majority
of potential adverse impacts will occur during the construction phase of the KAIP. However given that this
primarily involves the rehabilitation of existing infrastructure, mitigation measures should be able to alleviate or
lessen any potential negative impacts. The key potential impacts that are being mitigated are:
- Solid waste generation
- Soil erosion through vegetation clearing and excavation
- Hazardous materials handling and storage (potentially including asbestos and hydrocarbon contaminated
soils)
- Noise and vibration disturbances from machinery and transportation of materials
- Air pollution from dust and equipment
- Traffic disruption during construction activities
- Transport of equipment and materials from the port and around Tarawa
- Disposal of waste materials
- Safety hazards for workers and users of the facilities where upgrades are occurring
- Water demand management for freshwater resources
- Wastewater discharges
- Construction camp establishment and dis-establishment
This BEIA and EMP is designed to address these issues through:
- Implementation of this EMP through the Contractor’s EMP.
- Regular supervision and monitoring of the implementation of the EMP (refer EMP monitoring plan).

1.0 Introduction
1.1 Background
The Pacific Aviation Investment Program (PAIP) is funded by the World Bank (WB) and has the development
objective to (i) improve the safety, security, efficiency, management and environmental sustainability of airports,
and (ii) improve regional harmonization of aviation safety standards. Phase I of the Program, for which this Basic
Environmental Impact Assessment (BEIA) and Environmental Management Plan (EMP) is prepared, includes
Kiribati, Tonga and Tuvalu. This site specific BEIA and EMP has been developed for project work at Bonriki
International Airport (TRW) on Tarawa.
Air transport is the most efficient mode of transport in Kiribati due to the distance of its islands (stretches some
4,000 km). Kiribati operates two international airports with Bonriki International Airport (TRW) being the primary
gateway to Kiribati. The Ministry of Communication, Transport and Tourism Development (MCTTD), through the
Civil Aviation Directorate (CAD) is responsible for both the administration and regulation of the civil aviation sector
along with operation of the airports.
The Kiribati Aviation Investment Project (KAIP) was established to implement the PAIP and manage works
associated with the airport upgrades. The KAIP aims to improve Kiribati’s airport infrastructure, meet International
Civil Aviation Organisation (ICAO) standards (for international airports), and to ensure sustainable operation of the
civil aviation sector in Kiribati.
In May 2011, an overarching EMP (AECOM, 2011. Kiribati Aviation Infrastructure Investment Environmental
Management Plan) was published for all components of the KAIP. The overarching EMP is in compliance with WB
Policy OP/BP 4.01 Environmental Assessment and national legislation, and provides a framework for mitigation of
the projects’ impacts and development of a site specific EMP incorporating the detailed design, construction and
operational stages. Consultation and public disclosure was undertaken during the project preparation phase with
details of stakeholders and outcomes included in the National Task Force report titled Consultation Report Pacific
Aviation Investment Program – Kiribati dated 8 September 2011. This BEIA and EMP builds on the overarching
EMP and details environmental impacts and mitigation measures specifically for TRW and incorporates details of
the final detailed designs.
1.2 KAIP Objective
The KAIP aims to improve Kiribati’s airport infrastructure, meet International Civil Aviation Organisation (ICAO)
standards (for international airports), and to ensure sustainable operation of the civil aviation sector in Kiribati.
1.3 BEIA and EMP Objectives and Scope
The KAIP is a category B project under WB environmental and social screening guidelines and requires
development of the project EMP. Due to the nature of the project it is expected that environmental impacts will be
site specific, few if any are irreversible, and mitigation measures can be readily designed and implemented.
This BEIA and EMP is a dynamic document to be updated if there are changes to the project scope, detailed
designs, or if further information becomes available as a result of consultation with stakeholders and the general
public. The objective of the BEIA and EMP is to provide a framework for managing the airport upgrade works in a
manner that incorporates the principles of environment sustainability while minimising potential adverse effects on
the local community and the environment.
To achieve this objective the BEIA and EMP outlines the mitigation measures required for avoiding or minimising
the potential impacts of the works and provides a monitoring program to confirm effectiveness of the required
mitigation measures. Roles and responsibilities are clearly defined for all stages of the project works and their
execution. The BEIA and EMP also provide the details of how the community and stakeholders are to be engaged
and the mechanisms for ongoing consultation and communication.
This BEIA and EMP is limited to the scope of works as described in Section 2 of this document and addresses
impacts and mitigation measures identified at each stage of the project’s execution, namely detailed design,
construction and operation. This BEIA and EMP builds on the impacts and mitigation measures as identified in the
overarching EMP and includes outcomes of the consultation undertaken to date. This BEIA and EMP will be
included in the bidding documents for construction contractors and form the basis of the Contractors’ EMP.

1.3.1 Environmental Safeguards Document Hierarchy and Development
The PAIP has an Environmental and Social Management Framework (ESMF) which outlines the key steps and
procedures in screening and assessment of environmental and social issues related to the PAIP (generally). The
ESMF sets out the principles, rules, guidelines and procedures to assess the environmental and social impacts. It
contains measures and plans to reduce, mitigate and/or offset adverse impacts and enhance positive impacts,
provisions for estimating and budgeting the costs of such measures, and information on the agency or agencies
responsible for addressing project impacts. It defines roles and responsibilities, and provides guidance for the
Implementing Agency (IA), Executing Agencies (EA) (respective country’s ministries) and the respective countries
Civil Aviation Authorities for developing the environmental and social safeguards documents in compliance with
respective WB operational policies (namely OP/BP4.01, OP/BP4.12, OP/BP4.10) and respective country
environmental requirements.
The EMP is a dynamic document which is updated as and when project scope, detailed designs or further
information becomes available, thus creating a hierarchy of documents as the project progresses. The diagram
below shows the hierarchy and development of these documents culminating in the development of the
contractor’s EMP which specifically details how the contractor will implement requirements of the EMP. Issues,
impacts and mitigation measures identified in superseded EMPs are incorporated into subsequent versions
unless they have been addressed through design or other means, in which case this is identified in the EMP. Only
those documents in the diagram below showing a date have been drafted, all others are either in progress or are
yet to start.
Figure 1 Environmental safeguard document hierarchy
In order to finalise this BEIA and EMP for inclusion with the pavement (runway), and navigational aids and lighting
contractor procurement bid documents for the KAIP, the information pertaining to the terminal has been left at the
draft detailed design stage. An addendum to this BEIA and EMP specifically addressing the final detailed design
of the terminal will follow when the detailed design phase is finalised and confirmed by MCTTD.
1.3.2 Social Safeguards Document Development
In May 2011, a Resettlement Policy Framework (RPF) (AECOM, 2011. London – Cassidy Airport Road Kiritimati,
Bonriki Airport Tarawa Investment Sub-Projects; Resettlement Policy Framework) was developed for the KAIP

due to the initial trigger of the WB OP/BP 4.12 Involuntary Resettlement for outstanding land lease issues
regarding the location of the Terminal and potential resettlement requirements as the result of the construction of
a perimeter fence around TRW. The Social Safeguards Report (AECOM December, 2013) was developed as the
agreed perimeter fence location does not require any physical resettlement at this point, so a Resettlement Plan
was not necessary. The Social Safeguards Report is set within the Resettlement Policy Framework.
1.4 BEIA and EMP Methodology
The methodology used to develop this BEIA and EMP is as follows:
- Review the ESMF and overarching EMP including consultation outcomes to inform the Design and
Supervision team of specific issues or items for detailed design.
- Prepare for field survey and organise site visits, inclusive of specific requirements as identified in the
overarching EMP, Consultation Report and ESMF.
- Conduct field survey using the overarching EMP, ESMF and an environmental screening checklist as a
basis for assessment.
- Liaise with the Design and Supervision teams regarding any findings which may influence detailed design.
- Draft the TRW BEIA and EMP based on overarching EMP framework and consultation outcomes and
update with information obtained from the field survey and detailed designs.
- Submit to the Technical and Fiduciary Services Unit (TFSU) and MCTTD/Environment Conservation Division
(ECD) for review prior to consultation. Update according to comments and feedback from TFSU and
MCTTD/ECD.
- MCTTD to undertake consultation at TRW with this site specific BEIA and EMP available in hard copy and
posted online. Incorporate outcomes as required from consultation into final TRW BEIA and EMP to be
included in bidding documents.
- Submit to TFSU and MCTTD/ECD for final review.
A number of PAIP concept design, detailed design and supporting assessment reports have also been reviewed
in compiling information regarding the scope of the project and identifying potential effects and mitigation
measures. Some of these reports are still in draft form and changes may impact on the type and scale of potential
effects and opportunities to avoid these impacts or potential mitigation measures that may need to be
implemented. Any changes in these documents should prompt a review of this BEIA and EMP and be updated
accordingly. The documents are listed as follows at the stage of development at the time of writing this version of
the BEIA and EMP.

2.0 TRW Upgrade Description of Works
2.1 Overview of Works
The KAIP consists of four primary tasks:
- Airport pavements
- Airport security fencing
- Airport terminal and security
- Airport navigational aids
2.1.1 Runway Pavement Design
The 09-27 runway formation at Bonriki International Airport was reportedly constructed by the United States in
1943; following the battle of Tarawa, during WWII. Since then it has been developed into a civilian airport and is
understood to have received a range of strengthening and surfacing works over the course of its life.
Currently the Bonriki runway surface is in poor condition. The main observable surfacing defect is the flexural
cracking and breaking up of the top asphaltic layer at localised areas. This is considered to be due to a
combination of environmental distress combined with water infiltration. The construction profile of the pavements
results in a tendency to trap water between the old and new surfacing layers which compounds the problem.
Surfacing repairs and a structural overlay are urgently recommended to keep the runway and airport operational.
The runway shoulders are aged with the asphaltic surfacing heavily oxidised. It is recommended that due to the
low priority and rarity of aircraft loading, these shoulders receive a bitumen rejuvenation surface treatment to
preserve them from continuing environmental effects.
The design scope for TRW is the resurfacing or rehabilitating and upgrading the runway, taxiway and apron for a
projected life of 20 years before any further resurfacing or major maintenance work is required. It is proposed that
the design aircraft for the TRW structural asphalt overlay is the current regular operation of B737 aircraft variants,
operated by Air Pacific. The B737-8 is the most onerous in terms of wheel loading of the current Code C jet
aircraft variants operated by commercial airlines in the Pacific region (similar sized alternatives include the A320
variants and the B737-700 which are all less onerous).
We note TRW also receives a range of infrequent C130 and P3 Orion operations which will also be included
within the detailed pavement design.
The existing runway has an Aerodrome Reference Code of “4C” this is summarised as follows:
- The code number “4” referring to the runway length being greater than 1800m.
- Intended to service aircraft up to a Code “C” physical size (wingspan up to but not including 36m).
AECOM have completed the final detailed design for the agreed runway rehabilitation works scope.
The following volumes of materials have been estimated (subject to change based on final designs and outcomes
of the procurement process).

The taxiway and apron experience extensive flooding with standing water remaining for several days after heavy
rainfall events. The apron area also has three pairs of abandoned fuel hydrant systems. These are in poor
condition and are no longer in service. Currently commercial aircraft operating into TRW refuel using the local
mobile fuel tankers. AECOM recommend that the hydrant heads and concrete surrounds are removed and the
pipelines are slurry-filled and capped off.
In order to comply with NFPA 415 requirements, the apron should drain away from the terminal building for the
first 15.2 m or greater. The existing apron cut off drain is currently positioned in a suitable location to achieve
compliance with this standard. Unfortunately this has been concrete backfilled in the past and is in poor condition.
A replacement slot drain will be implemented, this comprises:
a) A preformed 300mm wide grated rain unit, with aircraft rated gratings (which are bolted down rather than
loose fit).
b) Fuel interceptor drainage pods which are reticulated to capture low volume flows, with high volume rain
events bypassing the interceptor by way of an overflow weir in the main drain line interception sump.
Figure 2 Diagrams of typical preformed slot drain units & an example of the proposed oil separator pod
A perforated slot drain is recommended which is suitably rated for aircraft wheel loads. These have proven
durability characteristics within the NZ airport market under regular Code C and code D aircraft usage.

The fuel spill interceptor “pods” are fabricated from high density polypropylene. These are a relatively simple and
low maintenance installation.
Additional fuel spill pod units are proposed for installation onto the existing main drainage line from the central
apron area sumps and into a new sump proposed for the south east edge of the apron which drains the proposed
second aircraft parking position. The overall apron drainage plan is shown in Appendix A.
2.1.1.1 Western Taxiway Area Flooding issue
Flooding of the western taxiway area due to the under vertical curve of the taxiway and apron slopes are
addressed by:
a) Installing a soak away drainage sump to the east of the taxiway to replace the failed outlet drainage system.
b) Crowning of the taxiway to improve strength, which also breaks the flow path eastwards.
c) Installation of a slot drain between the taxiways to reduce the apron flow westwards to the taxiway sag area.
d) Sumps and gratings include aircraft load rated lids.
Selected final detailed designs are provided in Appendix A.
2.1.2 Perimeter Fence
The final agreed fence alignment, as approved by Cabinet (R.Timau, personal communication, 8 October 2013),
is presented in drawings AV 1170 / 1171, copies attached in Appendix A. The minimum 150m runway strip
extents and minimum runway end areas are also shown on these drawings for comparison.
Where possible, the runway fence has been moved to just clear of the minimum runway strip dimensions (150m
wide runway strip), and a conventional 2.44m high ICAO type security fence is planned to be constructed. At the
runway ends, the Government, in consultation with the main international Airline – Air Pacific, have instructed
AECOM to leave the runway ends unfenced. The 2.44m high security fence terminates at the strip edge – runway
end corner points. At the 27 runway end there is a significant seawall structure where the fence end terminates. At
the 09 runway end, the existing access road is to be realigned (by others) to the practical extents of the runway
end area around the end of the runway end safety area (RESA). The proposed road realignment is shown on
drawing AV1170, highlighted in orange, refer drawing attached in Appendix A.
The instructed lower height (1.5m) uPVC fence extends from the aircraft maintenance hangar (adjacent to the
main terminal complex) along the runway strip edge, around the runway 09 end area and connects to the existing
public road at the 150m runway strip offset position. The Government advises that the 09 runway end road will be
temporarily closed to vehicular traffic during operations by international aircraft. The low level fence is primarily a
means of delineating and restricting public vehicles access to the operational runway area (which is currently
extensively used as a means of public access from one end of the airport to the other).
A number of strategically placed pedestrian gates are planned to facilitate across runway strip pedestrian foot
traffic during non-aircraft operational times. This lack of access to vegetable growing areas on the opposite side of
the runway has been a major issue in the past (and the likely cause of public demolition of previous fences as a
consequence).
Vehicle gates are positioned on the 27 end to allow public access across the runway end area, in a controlled
fashion. A vehicle gate is also positioned at the 09 runway end to allow emergency vehicle access clear of the 09
runway perimeter if so required. Two controlled access gates are planned for at the Terminal building area as
currently exists.
All cross runway accesses are to be operated under airport authority control. A typical pedestrian gate detail has
been developed to allowed controlled access across the runway strip area, refer Figure 2.

2.1.3 Terminal
AN ADDENDUM TO THIS BEIA and EMP WILL FOLLOW ADDRESSING SPECIFIC IMPACTS AND
MITIGATION MEASURES ASSOCIATED WITH THE FINAL TERMINAL DETAILED DESIGN
The existing TRW Terminal, built in 1977, is in immediate need of interior and exterior maintenance work and is
undersized for the existing Peak Hour of to 96 departures and 96 arrivals. The Terminal concepts are based on
providing additions and upgrades to the existing Terminal.
Due to budgetary constraints, a staged process has been proposed in developing the Terminal and meeting all
design objectives. Through a series of design workshops and iterative design process (as detailed in the Kiribati
Draft Final Design Report – Airport Terminals & Security, 10 September 2013) a number of options were
developed with Option 3 selected as the final stage 1 terminal design option. The Recommended Option 3 Final
Stage 1 Terminal Design provides additional departures and arrivals passenger and bag processing capacity by:
- Re-planning and re-assigning existing internal Terminal areas.
- Expansion of the bag reclaim hall and provision of a new 17m presentation length bag reclaim conveyor.
- The addition of a new check-in hall that replaces the outdoor public space between the existing departures
and arrivals wings.
Option 3 provides Terminal improvements throughout the Terminal, adopting a reduced area allowance compared
to IATA LOS C space standards to meet PAIP Budgets. At peak times, temporary passenger congestion and
processing delays can be expected. Nevertheless Option 3 will provide significant level of service improvements
during Code C aircraft arrivals, albeit not to an IATA LOS C standard. It is also noted that while the 17m bag
reclaim conveyor proposed is a significant improvement compared to the existing undersized timber reclaim
bench, it does not meet the requirements for IATA LOS C for Code C operations (B738s or equivalent). A 35m
bag reclaim conveyor would be required to provide IATA LOS C. Bag Reclaim Hall congestion and delays will be
experienced for short periods during Code C jet international arrivals.
The primary constraints, in respect to the Stage 1 Terminal expansion, are:
- The aircraft parking apron which restricts expansion to the north-east.
- An existing aircraft hangar and other landside buildings restricting expansion at both ends of the Terminal.
The Terminal and Apron Precinct Constraints Plan (Figure 3) shows the main constraints (including buildings,
below ground services and airside operational areas) to be considered in the design of the Stage 1 Terminal
Expansion. The site for the proposed Stage 1 Expansion is constrained by an existing airport hangar and other
landside buildings as indicated in Figure 3. Some existing car park land will need to be used to accommodate the
expansion of the existing Terminal.

The Recommended Option 3 incorporates Environmentally Sustainable Design (ESD) as outlined below:
- Water collection and re-use.
- Improved natural ventilation.
- New energy efficient lighting.
- New dual flush, water saving toilets.
- Materials and finishes with low embodied energy.
- Floor finishes, adhesives, paints and sealers with low or no off-gassing of Volatile Organic Compounds
(VOC). Terminal Water Supply
The Terminal is currently connected to bore supply; this water supply will be retained for emergency use.
The new water storage tanks are to be equipped with fire brigade connections to allow any water stored to be
used for fire fighting purposes.
Domestic water pumps duty/standby pumps will draw water from the storage tanks complete with a pressurisation
tank, filters and controls as required to operate the system filling a header tank located at high level in the
Terminal. Weather protection of the pump set will be required.
A carbon filter will be fitted to the bore water supply to remove hydrogen sulphide odour. Terminal Waste
Water
Two new sanitary storage tanks will be provided. The tanks will be required to be periodically pumped out by a
collection service..
Selected concept design plans are provided in Appendix A.
2.1.4 Navigational Aids
New installations have been approved for the following Air Navigation Aids:
- Automatic Weather Station (AWS).
- Automatic Dependent Surveillance-Broadcast (ADS-B) - Currently on hold pending independent review by
the funding provider.

- New Air Traffic Control (ATC) radio installations.
- Replacement Precision Approach Path Indicator (PAPI) installation for approach runway 09.
- New PAPI installation for approach Runway 27.
- New Non-Directional (radio) Beacon (NDB)/Distance Measuring Equipment (DME) installation.
- Diesel generation unit
AWS installations are usually located adjacent to the primary runway touch down zone however this is not
possible at TRW due to the site constraints on the primary approach (09 runway). Bonriki village is located on the
southern side of the runway with ponds on the northern side of the runway. Therefore the preferred arrangements
for TRW are:
1) Wind sensor (anemometer) location: On top of the windsock at the 09 end of the runway.
2) Wind sensor data connection: Fibre optic cable in new ducts to other sensors location.
3) Wind sensor power connection: Hard wired in new ducts.
4) Other weather sensors location: ATC compound.
5) Sensor power supply: From the ATCT supply.
6) Central PC location: Spare office space on the second floor of the ATCT facility.
7) PC power supply: From the ATCT facility supply.
8) Sensor to PC communications: Multi-core copper cable.
9) Remote display: ATCT cab.
The new ADS-B system should be installed in the ATCT facility compound, with the preferred arrangements as
follows:
1) The new ADS-B antenna should possibly be installed close to and north east of the ATC tower, clear of the
primary sight lines. Interference checks will need to be done with the other transmitting systems.
2) Equipment includes antenna, equipment shelter, ducted power supply and ducted communications cables.
3) Location for the equipment rack could be in the spare second floor office. The area shall be air conditioned
using non- hydrochlorofluorocarbon (HCFC) gases in the unit(s).
4) The controller display system to be installed in the tower cab.
5) The design team will check the selection of equipment with Airways International for compatibilities with the
regional network.
The existing approach runway 09 PAPI is in sound working condition, though spare parts are difficult to obtain.
New PAPI boxes are to be retrofitted to the existing installation. New control and power cabling is to be provided
and reticulated via a duct and pit reticulation system back to the ATCT facility. A new approach runway 27 PAPI is
recommended which will include a new four box PAPI installation. New control and power cabling is to be
provided and reticulated via a duct and pit reticulation system back to the ATCT facility.
A single PAPI light unit contains three 6.6 A, 200 W lamps, three reflectors and red filters, six lenses, a lens
shield, a printed circuit board, and a tilt switch assembly. PAPI lights are only activated when an aircraft is
approaching for landing. As TRW does is not able to receive night flights the only time the PAPI will be used at
night time is if there is an emergency landing. There should be no effects of light pollution as a result of the PAPI
light units.
A new NDB unit (including aerial mast) adjacent to the ATCT compound has been recommended so the unit can
be removed from the public car park area. The new aerial mast is to be located behind the ATCT facility clear of
sight lines.
The primary power supply to the ATCT facility is from the Government power supply utility. The transformer is
located at the 09 runway end. A new diesel generator will be installed as the secondary airport supply and
essential power supply for the navigational aids, PAPI, ATC facility and critical elements of the terminal building.
This unit should be located in the ATCT compound.

A new pit and duct system connecting the proposed new windsock and existing PAPI along the northern side of
the runway to the proposed AWS installation (in the ATCT compound) and reticulated into the ATCT facility is
required. The second duct line will run south around the 27 runway end and up to the new 27 PAPI location. The
pit and duct system will be run within the runway 150 m runway strip. Details of the pit and duct system are as
follows:
- 4,515 m of ducts will be provided with minimum 750 mm cover.
- Separate draw-in pits and change of direction pits will be provided for each 63 mm diameter duct to provide
segregation between the PAPI primary cables and the AWS anemometer cables (reticulated to the 08 WDI).
- SIT pits will be provided at each PAPI box.
- Change of direction pits will be outside the runway grade strip and will be 0.9 m x 0.9 x m 1.0 m pits with
Class D lids.
- SIT pits will be used as intermediate cable draw pits. Draw pits will be provided at intervals of no more than
180 m along straight runs.
A minimum 500 mm cover of compacted controlled low strength material (CLSM) fill. The sand and hardfill
required for the backfill of trenches will make use of material from the excavations associated with the trenches,
pits and foundations for the AWS pads. Material from other sources (e.g. the beach) will not be used. Concrete
mixing will be subject to the requirements of this EMP.
Old equipment and material associated with the airport navigation equipment which are obsolete and cannot be
reused or recycled on island must be removed from island at completion of project works.
Selected detailed design drawings and plans which best show the physical works are provided in Appendix A.
2.2 Alternatives
The airport is an existing infrastructure which requires maintenance work to ensure continued operation.
Alternatives regarding design approach and methodology were explored however budgets and constraints around
land and natural resource availability limited the selection of design and construction methodology. The designs
and proposed construction methodology have been selected based on the most effective use of natural
resources, labour, ease of ongoing maintenance, effects on the local environment and community and in the case
of the Terminal ability to build onto the design at a later date as and when funds are available.
The option to not do any rehabilitation work associated with the KAIP would be detrimental to the community and
safety of flight passengers and airport staff as the airport would be forced to close. Currently the Bonriki runway
surface is in poor condition. The main observable surfacing defect is the flexural cracking and breaking up of the
top asphaltic layer at localised areas. This is considered to be due to a combination of environmental distress
combined with water infiltration.
Emergency repairs were implemented in early 2012 to address localised areas of badly deteriorated surfacing.
AECOM’s recent inspection has confirmed that there are several additional areas, though relatively small, that the
surfacing is badly fatigued and on the verge of breaking up. Surfacing repairs and a structural overlay are urgently
recommended to keep the runway and airport operational. The TRW runway is considered to have the highest
priority for rehabilitation works overall under the PAIP programme. Although patching of the surface has proven to
be a reliable interim solution, it is only a short term holding repair to allow time for the planning and efficient
implementation of a full resurfacing program.
The existing TRW Terminal, built in 1977, is in immediate need of external maintenance work and is undersized
for the existing Peak Hour, thus creating an undesirable experience for passengers and staff working at the
airport. Currently the Chatterbox Café (located in Bikenibeu) provides additional check-in facilities including
issuing of boarding passes and weighing luggage. The café is attached to Tobaroi Travel who have been
authorised to provide this service. Luggage is still required to go through security screening at the airport.
2.3 Construction Methodology
The perimeter fence followed by the runway pavement will most likely be the first components of the KAIP to be
started followed by the navigational aids and lastly the construction of the terminal. The perimeter fence will most
likely be constructed after the runway pavement works, however exact timing will be dependent on the outcome of
community consultation. The contracts for the physical works for each component have yet to be awarded so the

Assessment - Bonriki International Airport (TRW) Final Draft
13-Dec-2013 Prepared for – Ministry of Communications, Transport and Tourism Development – Co No.: N/A
11
precise construction methodology is unknown. However the conceptual and detailed designs provide an indication
of the nature of the work. The Contractor’s implementation EMP will address specific methodological measures or
impacts.
2.3.1 MOWP
The Method of Works Plan (MOWP) is a required document for any major construction works within the
boundaries of an airport. The MOWP sets out the operational requirements for maintaining a functioning airport
throughout the construction process. It includes the concessions and alternative arrangements that may need to
be made (e.g. alternative aircraft parking apron) and staging of the construction process while ensuring the safety
and security of all personnel, the community and aircraft and continued operation of the airport throughout
construction works.
2.3.2 Materials and Equipment
All materials and equipment for each component of the KAIP will need to be imported. All cargo whether air or
ship will need to be processed in accordance with Kiribati quarantine and customs laws which require fumigation
(proof of) of materials and equipment and declarations by personnel (specifically regarding communicable
diseases).
All equipment and materials (unless used up) bought into Kiribati for the project must be removed from Kiribati at
completion of the project. Old equipment no longer serviceable or waste material onsite (TRW) must also be
removed from Kiribati. The exact types of equipment will be decided by the contractor(s) but may include
machinery used in construction activities (e.g. dozers, asphalt pavers, trucks and excavators) or machinery to
support construction processes (e.g. proprietary wastewater treatment unit, water purification unit, asphalt plant).
Excess materials not used (and unable to be re-used or recycled on island) may include excess bitumen, used
drums (for fuel, oil or lubricants), packaging from materials and equipment (particularly plastics), contaminated or
hazardous material (e.g. soil, used spill kit material, building material from demolition). Further information
regarding solid waste impacts and management are provided in Sections 6.3.1 and 7.9.
2.3.3 Aggregate Supply
Aggregate sources on Tarawa are very limited. The Environmentally Safe Aggregates for Tarawa (ESAT)
European Union funded dredging operation implemented by the Secretariat of the Pacific Community’s SOPAC
Division is a potential source of aggregate. However, timing availability, quantity and quality of the material is still
to be determined. Until further detail can be ascertained on the suitability of the aggregate from the ESAT
dredging operation the detailed design has been completed on the assumption all aggregates for the overlay
should be imported from an off shore supply source. The most likely suitable offshore source is the Standard
Concrete Company from Fiji. Contractors will be given the option of sourcing materials from alternative locations.
There will be strictly enforced material inspections and testing program from the Contractors selected quarry
source at an initial acceptance stage and retesting again prior to loading for shipment to site. Import requirements
will also be enforced. Due to the uncertainty regarding the ESAT aggregate this BEIA and EMP assumes all
aggregate material will be imported. If the ESAT project is confirmed as being able to supply some or all
aggregate materials this BEIA and EMP or the Contractor’s EMP will be updated to reflect this.
2.3.4 Construction Camp and Lay Down Areas
Land availability on Tarawa is scarce and so there are not many options for positioning of the construction camp.
The construction camp will be utilised by all project Contractors (pavement works, fencing, building and
navigational aids) at differing times so the scale of the camp will vary. The greatest land area required will be for
the pavement works (runway) component of the KAIP as the equipment and aggregate requirements are the
greatest. It is estimated that 1 hectare of land will be required for the duration of the KAIP construction works. The
proposed location for a construction camp has yet to be determined. This will be worked out through the detailed
design and procurement phase. The construction camp is not a residential camp, existing local accommodation
will be used.
The exact details of the location, size and site management (health and safety, solid waste management, water
management and wastewater management) will need to be decided by the Contractors in consultation with
MCTTD. Final approval of these details will be required by MCTTD before the construction camp can be set up
and documented in the contractors’ EMP.
The construction camp size should be kept to a minimum, be fenced and materials and equipment kept secure to
prevent access and use by non-authorised personnel. There are no existing hard stand areas available for stock

12
piling or bunded areas (secondary containment) for hazardous substance storage. Vegetation clearance along
with temporary hard stand and bunded areas will need to be constructed. Noise, dust, vibration and increased
traffic are impacts that can negatively affect communities and sensitive receptors.
Transport to and from the construction camp, particularly of materials and equipment, must occur on the existing
road network and measures undertaken to prevent dust, noise and vibration nuisance (e.g. wheel wash, covering
of loads, servicing of vehicles). If the transport of material or equipment is likely to impact on normal pedestrian
and vehicle traffic or pose an increased safety hazard, consideration should be given to moving these items
during off peak times. Hard stand areas must be available for storage of hazardous substances and other
equipment that poses a potential risk to the environment (e.g. leaking lubricant from machinery). Runoff from hard
stand areas used to store machinery will need to be collected and treated (e.g. oil water separator) to prevent
contamination of soil or water bodies (surface and underground). Hazardous substances (e.g. fuel, lubricants or
oil) must be stored in a bunded area which is constructed with an impermeable base and water tight walls to
contain the larger of 110 percent of the largest tank/container or 25 percent of the combined tank volumes in
areas with a total storage volume equal or greater than 1,000 litres1. Solid waste and wastewater must be
managed in such a way to prevent the spread of vector-borne diseases and contamination of soil and water
bodies. There are a number of small landfills in South Tarawa which are managed by the town councils and
MELAD. However there is pressure on the landfills and so all solid waste not able to be re-used either by the
project or community must be removed from island at completion of the project works. There is a limited saltwater
flushed sewage system on the island that services Betio, Bairiki and Bikenibeu, it does not extend to Bonriki and
the airport site. Therefore temporary toilets and disposal or treatment of wastewater will need to be in accordance
with the MPWU and ECD’s advice (for example construction and training in use of compositing toilet facilities).
All occupational health and safety requirements must be in place and workers trained in necessary procedures
(e.g. spill response plan). Personal protection equipment (PPE) needs to be available to workers as required (e.g.
high visibility vest, safety boots) and processes in place for obtaining relevant PPE.
Temporary equipment parking and small scale material storage (lay down area) may be required to reduce the
need to move equipment and supplies from the construction camp throughout the day and thus potentially impact
road users and residents (e.g. dust, noise, road safety). All temporary stockpiles must be kept small (no higher
than 2m) and bunded to prevent dust and sediment laden runoff being generated. If need be the stockpiles should
be wetted or covered to prevent dust. Lay down areas should not be sited near sensitive receptors (refer Section
5.4) nor the coast. Any land required for a temporary lay down area will need to be negotiated with the landowner
or lease holder. Temporary equipment storage areas within the air traffic control tower compound and at the
eastern end of the runway have been proposed (refer to Appendix A for plan showing proposed locations). These
temporary parking and lay down areas will be managed in accordance with this EMP and the main construction
camp.
2.3.4.1 Construction Camp Location
As previously stated the location of the construction camp has yet to be confirmed and details of the location, size
and site management (namely health and safety, solid waste management, water management and wastewater
management) will need to be decided by the Contractors in consultation with MCTTD. Final approval of these
details will be required by MCTTD and submitted to ECD before the construction camp can be set up.
The contractor’s EMP will need to document the site specific management and include a site layout plan,
identifying work areas (e.g. equipment parking, workshops, stockpiles, waste collection, wastewater treatment,
offices including sanitary facilities for workers, hazardous substances and material stores, and freshwater supply).
The mitigation measures identified in this EMP will need to be implemented on the construction camp as well as
work sites at the airport.
2.3.5 Duration and Timing of Construction Activities
Four separate contracts will probably be awarded for the four types of work, namely pavement rehabilitation
(runway), terminal construction, perimeter fence installation and installation of navigational aids. As the
contractors have yet to be appointed the exact duration of each component is not yet known, however indicative
time scales are as follows in probable order of commencement.

Normal working hours are Monday to Friday, 8am to 6pm. Works outside of these hours will require permission
from MCTTD and ECD. Notice to affected parties and the public is also required for work outside normal work
hours at least 24 hours prior to work commencing. It is likely that the runway pavement works will need to work in
addition to the normal working hours during night time (6pm – 6am) in order to work around flight schedules to
ensure safe operations of the airstrip for incoming and outgoing aircraft.

3.0 Policy, Legal and Administration Framework
3.1 National Requirements
Kiribati is a republic with a constitution that was promulgated on 12 July 1979. There are a number of legislative
acts and regulations which pertain to the upgrade works at the airport. The more relevant pieces of legislation are
described below, this list is not exhaustive.
The Environment Act 1999 (2007 Amendments) is the primary environmental legislation of Kiribati which provides
for the protection, restoration and enhancement of Kiribati’s natural, social and cultural environment. The Act also
gives power to the ECD for the administration of the environment including providing for sustainable development
and implementing the Environment Regulations (2009). The Act outlines requirements for impact assessment and
statements relating to development. Applications are to be made to the Principal Environment Officer (PEO) for
development approvals. This BEIA and EMP address requirements of a Basic Environmental Impact Assessment
(BEIA) required under the Environment Act 1999 (as amended in 2007), Part IV, Section 33(1). The completed
Environment License application is included in Appendix G. At this stage the contractors for the different
components of work have yet to be appointed. The detailed designs for the runway pavement, perimeter fence
and navigational aids are complete and are described in Section 2.0.
Section 49 of the Environment Act 1999 (2007 amendments) empowers environment officers as Environment
Inspectors to implement and enforce the Environment Act in Kiribati especially on South Tarawa. The
Environment Inspectors carry out patrols on illegal activities such as sand and gravel mining and dumping of
waste. They are also responsible for review and inspection of proposed and ongoing development projects,
including the airport upgrades.
The Aerodromes and Air Navigation Aids Ordinance (1977) applies to: (a) all aerodromes (areas of land or water
for the landing and taking off of aircraft) licensed under the Air Navigation (Overseas Territories) Order 1977, and
all Government aerodromes; (b) all air navigation aids established under section 4, and the sites upon which such
aids are situated; and (c) all aerodromes, air navigation aids and the sites thereof to which the Minister may by
notice apply the provisions of this Ordinance. It allows for the Government to declare controlled areas for security
and safety around aerodromes and navigational aids and conduct maintenance as and when required. The Civil
Aviation Act 2004 (based on New Zealand legislation) provides for the administration and management of the civil
aviation sector in Kiribati including delegations of authority, functions, rules, licensing and security.
The Mineral Development Licensing Ordinance 1977 makes provision for the licensing and development of
activities relating to the utilisation of Kiribati’s mineral resources. Developments requiring minerals (the runway
pavement rehabilitation requires aggregate) to be sourced within Kiribati must apply for a Mining License and will
need a Quarry Management Plan in support of the Mining License application. Aggregate for this project will most
likely be sourced offshore (e.g. Fiji) from a licensed supplier and thus be subject to quarantine and import
regulations.
The Wildlife Conservation Ordinance (1977) allows the Minister to declare areas as wildlife sanctuaries and
protection of specific animal and bird species. Within a wildlife sanctuary no person shall hunt, kill or capture any
bird or other animal (other than a fish) or search for, take or wilfully destroy, break or damage the eggs or nest of
any bird or other animal. “Closed areas” are wildlife sanctuary areas which are only accessible by license holders,
wildlife wardens and public officers. There are no wildlife sanctuaries or closed areas on South Tarawa and none
specifically near the airport.
Land put aside for reserves has three main pieces of legislation. The Recreational Reserves Act 1996 allows for
land owned or leased by the Government to be reserved for recreational purposes for the use and enjoyment of
the people of Kiribati. The Prohibited Areas Ordinance 1957 provides for certain islands and their territorial waters
to be prohibited areas, set aside for conservation purposes. The Closed Districts Act 1990 allows for parts of
islands to be declared for conservation purposes.
The Land Planning Ordinance (Cap.48, 1977) is the legal instrument that allows for the designations of land for
specific purposes (e.g. water reserve protection) and defines a general land use plan as “indicating the use or
class of use to which every part of the land depicted thereon maybe permitted to be put on for development or
redevelopment”.

3.1.1 Environment License
The airport developments, and any construction work designed to enable the airport developments, are
environmentally significant activities (ESA) as defined in the Schedule of Environmentally Significant Activities
(Section 14.0) of the Environment Act 1999. Therefore an environment license is required in order to carry out the
developments as described in Section 2.0 of this TRW BEIA and EMP. The ECD (responsible for administering
the environment license application process) upon review of the environment license application and a draft
version of this BEIA and EMP has stated that a Basic Environmental Impact Assessment is required for the KAIP.
Upon receipt of the final BEIA and EMP the document will be publicly displayed and public comment invited. The
required contents of a basic EIA have been provided and are presented in Appendix E. The table in Appendix E
also provides references and comments as to where information requested in a basic EIA has been addressed in
this TRW BEIA and EMP.
The steps and likely timeframes for environment license applications which require a basic EIA are identified
below.

Application Guideline, Version 2 issued 2 September 2011)
As stated in section 3.1 the completed Environment License application is included in Appendix G. At this stage
the contractors for the different components of work have yet to be appointed. The detailed designs for the
runway pavement, perimeter fence and navigational aids are complete and are described in Section 2.0.
3.2 Regional Requirements
The Local Government Act 1984 establishes local councils (also named island, town and urban councils) that
have powers to regulate and administer a number of functions around utilities, agriculture, buildings and town
planning among other things. In accordance with this legislation Tarawa has three administrative councils:
- Betio Town Council (or BTC), on Betio Islet;
- Teinainano Urban Council (or TUC), from Bairiki to Bonriki (this is the council applicable to the project area)
PEO determines that the proposed activity requires the
preparation of an EIA.
Applicant prepares draft EIA.
PEO undertakes review. Includes review by other Ministries
and regional environment bodies as required.
PEO provides applicant with comments on the draft EIA
Timeframe: 2 to 3 months
Applicant address comments on draft EIA and prepare

- Eutan Tarawa Council (or ETC), for North Tarawa or Tarawa Ieta (all the islets on the east side north of
Bonriki, including Buota which is linked by road to South Tarawa).
TRW is within the Teinainano Urban Council’s jurisdiction and so any solid waste management issues will need to
be addressed with this Council.
3.3 International Obligations
Kiribati is also a signatory to a number of international agreements. Listed below are some of the more applicable
agreements to the type of activities of the KAIP. This list is not exhaustive.
- Convention to Ban the Importation into Forum Island Countries of Hazardous and Radioactive Waste and to
Control the Transboundary Movement and Management of Hazardous Waste within the South Pacific
region. (Adopted at Waigani, PNG on 16 September 1995)
- Convention for the Protection of the Natural Resources and Environment of the South Pacific Region
(Adopted at Noumea, New Caledonia on 24 November 1986) and the —
Protocol concerning Cooperation in Combating Pollution Emergencies in the South Pacific Region
Protocol for the Prevention of Pollution of the South Pacific Region by Dumping
- Agreement Establishing the South Pacific Regional Environment Program (SPREP Convention)
- Stockholm Convention on Persistent Organic Pollutants (Adopted at Stockholm on 23 May 2001)
There are also a number of international standards and operating procedures that the airport operations must
comply with (e.g. ICAO and CAANZ).
Due to the problems regarding solid waste on Kiribati and the need to export all non-recyclable or reusable waste
from the project the Waigani Convention and Basel Convention are particularly relevant and will need to be
adhered to in preparing hazardous substances (e.g. waste oil, lubricants, articles containing polychlorinated
biphenyls or asbestos) for shipping and final disposal at acceptable and licensed waste facilities. The conventions
outline the necessary information required for documents (notification and movement) and agreements that need
to be in place with the receiving territory.
3.4 World Bank Policy
The KAIP is a category B project under WB environmental and social screening guidelines and requires
development of the project specific EMP. Due to the nature of the project it is expected that environmental
impacts will be site specific, few if any are irreversible, and mitigation measures can be readily designed and
implemented. In accordance with the WB Operational Policy 4.01 Environmental Assessment this BEIA and EMP
includes information on mitigation, monitoring, capacity development and training, and implementation costs. The
BEIA and EMP outlines the potential environmental impacts and the measures needed to prevent, minimise,
mitigate or compensate for adverse impacts and improve environmental performance of the project.
The EMP is a dynamic document which must be updated as consultation and detailed designs of the project
components are finalised to ensure currently unanticipated impacts and revised mitigation measures are
addressed. Effective implementation of the EMP is a requirement of the funding agencies and local legislation so
monitoring is an integral component of implementation. A Monitoring Plan is included in Section 7 (and Appendix
C) of this BEIA and EMP. This BEIA and EMP is to form part of the bidding documents for contract(s) awarded
under the KAIP and will form the basis of the contractor’s EMP.

4.1 Physical Environment
4.1.1 Location and Geography
Kiribati is scattered over three island groups, the Gilbert Group, the Phoenix Group, and the Line Group and
stretches some 4,000km located between Longitude 170 degrees East and 150 degrees West in the Central
Pacific Ocean, on either side of the equator. See Figure 7 for the general location of Kiribati and a map of the
islands. The three groups of islands are coral atolls with the exception of Banaba which is a raised limestone
island. Of the 33 islands comprising the Kiribati only 21 are inhabited. The country has two international airports,
operating from Tarawa Island (Bonriki International Airport) and Kiritimati Island (Cassidy International Airport).

Figure 6 Kiribati location map and Islands
Kiribati’s exclusive economic zone (area of the ocean in which it controls fishing and other rights) covers more
than 3 million km2.
The Gilbert Group which is comprised of 17 islands has a total land area of 286 km2. Tarawa, an atoll in this
group, is home of the Kiribati government, the main port of entry, the main international airport, and is Kiribati’s
capital (shown in Figure 8).

Figure 7 Map of Tarawa showing the villages; South Tarawa from Betio to Buota and North Tarawa from Buota to Buariki
On South Tarawa, the construction of causeways has created a single strip of land from Betio in the west to Buota
in the northeast. Tarawa has a large lagoon, of over 500 km2, and a wide reef. TRW is located by the village of
Bonriki on the south eastern side of the atoll. Most of South Tarawa is less than 3 meters above sea level with an
average width of only 450 meters.
4.1.1.1 Land Use
Land at TRW is primarily leased from some 300 plus individual landowners (personal communication with
Tebutonga Ereata Director of Lands, 15 October 2012). Lease agreements are for a period of 99 years, with
approximately 40 years remaining on existing leases. The land where the terminal and car park are located is
currently under dispute and is awaiting a high court hearing as a recent hearing was unsuccessful in reaching a
decision. Local landowners claim the terminal and car park are not included in current lease agreements and the

Government claims that the land was naturally reclaimed as a result of the Bonriki causeway constructed in the
1970’s. Both MCTTD and the Lands Division are pursuing this case.
The northern side of the runway is designated water reserve protection area. Gardens and rudimentary shelters
directly adjacent to the airport leased area were observed as were more substantial homes and development at
the north eastern end of the runway (part of Te Kawai ae Boou, a division of Bonriki village). On the north western
side of the runway are saltwater/brackish water ponds. The south eastern and western side of the runway is
Bonriki village with the apron, terminal and car park extending between the eastern and western side of the
village. Beyond the village and terminal are fish farm aquaculture ponds (milk fish).
At the western end of the runway is the lagoon (approximately 90m from edge of runway) and the ocean at the
eastern end of the runway (approximately 18 m from the closest edge of the runway). Seawalls have been
constructed in two areas at the eastern end. The first is on the northern side of the runway, and the second is at
the end of the runway (eastern end). The seawall on the northern side is a concrete sandbag construction.
Erosion is occurring at the northern end of this seawall (refer to Figure 9). The road that goes around the eastern
end of the runway is adjacent to this eroded area and the runway pavement is approximately 40 m south.
Figure 8 Seawall at north eastern end of runway showing erosion and bags of collected sand
The seawall at the eastern end of the runway is more substantial and was constructed as part of the Kiribati
Climate Change Adaptation Program (refer Figure 10) However during high tide waves were observed
overtopping this seawall.

4.1.2 Climate
Tarawa has a tropical climate which is hot and humid and moderated by trade winds, most common are the north
easterlies and easterlies. The average high temperature is 31 ºC and the average minimum temperature is 25 ºC.
Average rainfall in central Tarawa is over 2,000 mm (White, 2011). Drought conditions are usually associated with
La Nina conditions and the current prediction is for neutral ENSO (La Nina/ El Nino) conditions to continue
through 2013. Rainfall is usually higher from December through to April, with September and October being the
driest months. Tarawa is not often hit by cyclones however storm surges are experienced frequently often causing
extensive flooding and strong winds.
4.1.3 Soils and Geology
Like other coral atolls and islands, the nature of the soil is derived from limestone which has been formed as a
result of coral formation over thousands of years. The poor and infertile nature of the soil is due to its alkalinity,
porosity and lack of essential elements which limits its ability to support plant life. Consequently, it is incapable of
supporting intensive agricultural activities.
The topsoil is thinly spread over most of the area with plant cover and other areas covered with wild bushes. Due
to their ability to withstand the harsh atoll conditions the predominant plants species that survive are coconuts
(Cocos nucifera), pandanus or screw pine (Pandanus tectorius), salt bush (Scaevola sericea), and other tolerant
indigenous plants and trees.
4.1.4 Water Resources
Freshwater resources on Tarawa come from two main freshwater lenses that supply water to most households.
The two lenses come from Buota and Bonriki. Freshwater lenses overlay the underground denser saltwater.
Freshwater lenses are usually shallow convex shaped water deposits which are readily influenced by rainfall and
the tides. Atoll freshwater lenses are particularly vulnerable to saltwater intrusion and anthropogenic pollution (e.g.
sewage) and the Tarawa freshwater lenses are no exception.
The highly porous nature of the soils in Tarawa allows for recharge of the freshwater lens however compaction
and increased areas of impermeable surfaces (e.g. roads or buildings) can greatly affect the recharge capability of
the catchment. The Government of Kiribati have declared water reserve protection areas over the Bonriki and
Buota freshwater lens in order to better manage the catchment areas. TRW is located within the Bonriki
freshwater lens catchment.
The water reserve catchment areas have infiltration galleries throughout the catchment to promote recharge of the
freshwater lens and also allow for extraction by skimming freshwater from the surface of the freshwater lens2.

These galleries will have a pump station for extraction and or a monitoring bore for collecting water quality
samples (refer Figure 11).
Figure 10 Bonriki water reserve catchment infiltration galleries and monitoring bore locations
Due to supply and water quality pressures on Tarawa’s freshwater resources water efficiency measures and
rainwater harvesting are to be incorporated into the terminal design. During the construction phase the Contractor
will be responsible for securing a water supply which does not adversely affect the community’s freshwater
reserves (e.g. their own mobile desalination plant and additional rainwater harvesting). There is a limited
reticulated water supply to households.
4.2 Biological Environment
4.2.1 Marine Biodiversity
The coastal areas of Kiribati are characterized by white sandy beaches, reef flats, reef patches, lagoons,
mangrove forests, extensive reef mud flats and sea grass beds. These areas contain a variety of habitats,
numerous ecosystems and marine organisms. The coastal areas support fishing, recreation, trade and
communication. The marine environment is a critical and strategic resource for Kiribati as it provides the mainstay
for subsistence.
Mangrove forests do exist on the lagoon foreshore. Replanting efforts are also underway to re-establish
mangroves along the airport causeway road. Mangrove rehabilitation is undertaken by the Government (MELAD
and Ministry of Education, Youth and Sports) with assistance from the International Society for Mangrove
Ecosystems (headquarters in Japan) and the World Bank funded project, Kiribati Adaptation Project (KAP). It
includes planting of mangrove in selected areas prone to coastal erosion and in areas to protect causeways.
Several types of mangroves are found in Kiribati namely the white mangroves (Sonneratio alba), the tongo
buangui (Bruguiera gymnorhiza), te aitoa (Lumnitzera littores), and the red mangrove (Rhizophora stylosa). While
the airport site is located close to the lagoon in some places (less than 50 m) there should be no impact on the
lagoon mangrove forests or replanting. Wastewater from site activities will be captured for discharge to land (or
treatment) and will not be allowed to flow directly into the lagoon or ocean.

Ministry of Fisheries and Marine Resources is responsible for the management of marine resources including
production of aggregates and sand from the coastal areas. Preventing the destruction of marine resources
including coral reefs is necessary. Therefore, all material to be used for the KAIP shall be sourced from approved
overseas quarries or borrow pits. Material for the runway will be imported as required (e.g. from Nauru, Fiji or
elsewhere). The project will also take necessary precautions and measures to ensure that the construction
activities will not pollute the lagoon environment.
4.2.2 Terrestrial Biodiversity
South Tarawa is a densely populated landmass which has undergone significant anthropogenic changes. There
are no natural forests of major significance in terms of size, age and biological diversity near the airport on South
Tarawa. Food crop trees of coconut (Cocos nucifera), breadfruit (Artocarpus sp), and pandanus (Pandanus
tectorius) dominate the landscape as do papaya (Carica papaya) and other fruit trees. Decorative species which
also feature prominently are casuarinas (Casuarina equisetifolia), hibiscus (Hibiscus sp), flame tree (Delonix
regia) salt bush (Scaevola sericea) and terminalia (Terminalia sp).
The vegetation cover of South Tarawa has little biodiversity conservation significance and has been affected by
the contamination of the freshwater lenses with salt water and subsidence crops require careful cultivation and
application of compost and nutrients to sustain the crops. While the vegetation cover has little biodiversity
conservation significance the vegetation that does exist needs to be preserved as food sources and providing
shade.
4.2.3 Rare or Endangered Species
The 2008 International Union for Conservation of Nature (IUCN) Red List identified a total of 88 species in Kiribati
which are threatened. None of the species identified as threatened are endemic and no species have been
identified as extinct. A total of 488 species were assessed and 6 bird, 1 mammal, 7 fish, 73 invertebrates and 1
reptile species were identified as being threatened. The IUCN regard the threatened status of animals and plants
as one of the most useful signs for assessing the condition of an ecosystem and its biodiversity. The IUCN Red
List of Threatened Species™ (IUCN Red List) is widely recognized as the most comprehensive, apolitical
approach for assessing and monitoring the status of biodiversity. The green sea turtle, hawksbill turtle, bay shark,
and the leatherback turtle are endangered.
As stated the location of the airport is not near any biological conservation areas and is located within the most
developed area of the country. However there is still potential for activities carried out in relation to this project to
encounter a threatened species. Mitigation measures to deal with these encounters have been identified in
Section 7 of this BEIA and EMP.
4.3 Socio-economic Conditions
4.3.1 Population and Demographics
The total population of Kiribati is 103,058 people (2010 Census). South Tarawa has an official land area of 15.76
km2 and a population of 50,182 (52% female), giving a population density of 3,184 people per km
2 however
density is expected to be higher than this due to not all the ‘official land area’ being available for residential
development (e.g. roads, conservation, the airport). South Tarawa experienced 4.4% growth between the 2005
and 2010 census. This growth is a mix of immigration from outlying islands and births (2.26% contribution to
annual population growth).

4.3.2 Education and Health
As the capital, Tarawa has education facilities catering for all levels of education, namely tertiary, secondary,
junior secondary (JSS), primary and pre-schools. A total of 12,195 children were enrolled in the primary, JSS and
secondary schools in South Tarawa in 2011, distributed as follows:
- Primary school enrolments were 6,442
- Junior secondary school enrolments 3,143
- Senior secondary school enrolments 2,610
School enrolments have not been increasing with the South Tarawa population increase.
At secondary level many students travel from their home island to attend school in South Tarawa, usually staying
with relatives. Secondary schooling is not compulsory in Kiribati and school fees are hard to afford for many
families.
At the tertiary level, the University of the South Pacific has a campus at Teaoraereke. There are also several
vocational schools including an institute of technology (KIT), maritime training centre (MTC), a fishing school
(FTC), a Police Academy, a nursing school, a teachers training college (KTC), a theological college (TTC) for
Ministerial Formation in the Churches at Tangintebu, and a pastoral institute (KPI) at Teaoraereke.
The main hospital is at Nawerewere in Bikenibeu area. Betio has its own hospital while the populated villages
have their own clinics. From Buota to Bairiki, there are 13 clinics, and Betio alone has 7. Some of these clinics are
special clinics for certain ailments or for counselling.
Kiribati has an extremely high incidence of water-borne diseases with an infant mortality rate amongst the highest
in the Pacific at 46 per 1,000 live births, which is attributed to infantile diarrhoea. The World Health Organization
(WHO) and health officials report an average of three outbreaks of diarrhoea annually directly linked to poor water
supplies, inadequate sanitation, unsafe practices and poor public hygiene.
4.3.3 Livelihoods and Economic Activities
The primary source of income in South Tarawa is from formal work (wage earners) but unemployment and under-
employment is high. In 2010 only 34% of urban people over 15 years of age (the labour force) were engaged in
cash work. Of the remainder, 21% were unemployed, 5% were engaged in voluntary or subsistence work, and
41% were not in the labour force (that is they were studying, retired, raising children or otherwise not available for
work). In total, two thirds (66%) of adults (over 15) in Tarawa are either out of the labour force, unemployed or
engaged in subsistence activities.
The Household Expenditure and Income survey showed that the average household on South Tarawa earns
$11,464 per year (including almost $4,000 “cash equivalent” for subsistence activities and imputed rent) but spent
$13,149 each year with half of this spending being on food.

4.3.4 Land Tenure and Rights
The land tenure system in Kiribati is complex and in areas like South Tarawa and conflict regarding resources and
“the public good” abound. The airport land has not been immune to these conflicts. A Social Safeguards Report is
being prepared for the KAIP to address access issues that may arise due to the perimeter security fence and the
land lease dispute regarding the terminal land.
There is a number of legislation that seemingly over-lap regarding land tenure, property rights and land use
planning within Kiribati. Land is owned by families with all members of the family having equal rights to build or
collect food from. The 2010 census showed that only 50% of South Tarawa inhabitants own the land they occupy,
29% is Government leased (which include Government buildings, sportsfields, small industry, port, airport, and
public housing).
The Land Planning Ordinance 1972, revised 1977, establishes the right of Government to set aside designated
areas, as was done with effect from October 1979 for the whole of Kiritimati Island (Subsidiary Legislation to
Section III). The Native Lands Ordinance 1956, revised 1977 establishes the principle of indefeasibility of native
title to land (S.4), though land may be alienated by the Crown (S.5(2)). The law recognises the concept of lease of
native land, as is the case with Bonriki Airport land. Lease may normally only be by native to native, or to the
State, and may not exceed a term of 99 years. Before registering a lease, the Court must be satisfied that the
terms are fair to both parties, and that the lessor has sufficient land left to support the family (S.11(2)). Payment of
land rent is prescribed (S.15), and payment of compensation is envisaged for damage by the lessee, or for
unlawful occupation (Ss.24 and 35). The Ordinance allows for improvements on leased land with the permission
of the owners, though does not address the issue of ownership of these assets or improvements on termination of
the lease and reversion of occupancy to the title holder or another lessee.
4.4 Projected Climate Changes and Impacts
The Pacific Climate Change Science Program (PCCSP) (part of the International Climate Change Adaptation
Initiative) conducts critical climate research and capacity building in Pacific Island countries. Information regarding
climate change projections was obtained from the BoM and CSIRO (2011) Climate Change in the Pacific:
Scientific Assessment and New Research (Vol. 2: Country Reports) produced by the Pacific Climate Change
Science Program.
Kiribati, like many other pacific atoll nations are already experiencing the effects of increased temperatures and
rising sea level. Sea level (satellite data) has risen by 1 to 4 mm per year since 1993. Sea level does fluctuate
throughout the year particularly during La Nina years which tend to record warmer ocean temperatures. The
annual mean air temperature (since 1950) has increased by approximately 0.184 ºC per decade on Tarawa.
Annual and seasonal rainfall data for Tarawa has not shown any significant trends (1950 to 2009).
The projected design life is 20 years for the runway, and 50 years for the upgraded terminal structure (or less for
specific components such as cladding). Climate change projections for 2030, 2055 and 2090 (relative to 1990)
were reviewed. The PCCSP report (as identified above) reviewed a number of climate projection models to
determine the most plausible representations of future climate in the pacific under the three emission scenarios
developed by the Intergovernmental Panel on Climate Change (IPCC). The three emission scenarios are: low
(B1), medium (A1B) and high (A2), for time periods around 2030, 2055 and 2090 (refer to Figure 12 for details of
emission scenarios).

Table 2 below shows the projected changes in annual average air temperature and sea level for the Gilbert
Islands (location of Tarawa island) for the three emission scenarios and the three time horizons. Sea level rise
should be considered when establishing the design terminal floor levels, in conjunction with the intended design
life and appropriate freeboard requirements.

In the short term (2030) the climate models prediction for rainfall do not increase (or decrease) significantly,
however by 2090 it is expected that rainfall will increase. There is only moderate confidence in the models
prediction. There is high confidence that the intensity and frequency of extreme rainfall days are projected to
increase. As most runoff from rain events goes to natural soakage this does not impact on the detailed designs.

5.0 Consultation and Stakeholder Engagement
5.1 Background and Approach
As required by WB Safeguards Policies and the Kiribati Environment Act consultation and disclosure of Category
B projects must be undertaken with project affected groups (stakeholders) and non-government organisations
(NGO). The potential environmental and social impacts of the project require the opportunity for discussion and
review during the environmental assessment/EMP process to inform detailed design and mitigation measures.
This BEIA and EMP will remain a draft until public disclosure and consultation has been completed. This will allow
for the BEIA and EMP to be updated with details of consultation and disclosure as and when this is completed.
Disclosure and consultation will be the responsibility of MCTTD either directly or through their nominated
Consultant. Consultation regarding this BEIA and EMP will be undertaken in conjunction with the requirements of
the KAIP RPF as the outcomes of consultation specifically regarding the perimeter fence will directly influence the
designs.
5.2 Outcomes of Consultation to Date
The overarching KAIP EMP and Resettlement Policy Framework was publicised and consultation held at with the
neighbouring community on 9 August 2011. Subsequent consultation with the Bonriki community has been
undertaken on 13 and 15 April 2013. Minutes from the consultation in August 2011 and April 2013 are presented
in Appendix F.
5.2.1 Consultation Summary 9 August 2013
The following four communities met with Government representatives for the KAIP project on 9 August 2011:
- Kiribati Protestant Church (KPC) maneaba in Bonriki
- Roman Catholic maneaba in Bonriki
- Tekawai ae Boou maneaba
- AA maneaba in Bonriki
The community at the KPC and Tekawai ae Boou maneaba tend to be newer land owners and settlers to the area
when compared to the community at the Catholic and AA maneaba in Bonriki. The Catholic maneaba had the
largest number of attendees (total 50, comprising nine women) followed by the AA maneaba meeting (total 39,
comprising nine women). The key issues the community expressed concern about are shown in the following
table. Some of these issues could not be addressed at the time due to the project stage (e.g. detailed designs not
complete) or are outside the scope of the KAIP.
Table 3 Consultation outcomes and KAIP response
Consultation Outcome Response
Borrow sites, protection of
lands and the lagoon.
No borrow sites on South Tarawa are to be used to source material for the KAIP
construction works. All material will be imported (subject to fumigation and quarantine
requirements).
Flooding and insufficient
drainage
Detailed designs include new drainage system to prevent flooding around apron area.
These will require ongoing maintenance to ensure they do not become blocked.
Fence and restricted access Pedestrian gates have been included in the detailed designs. The agreed alignment
of the perimeter fence means that vehicle gates are no longer required. General
support for the fence as a safety precaution.
Waste disposal – what
waste to be generated and
where will it be disposed of?
Construction type waste includes milled asphalt from the runway surface, building
materials from the terminal and old electrical equipment. Some household type waste
will be generated by the workers. All waste is to be collected and stored within the
construction camp for re-use, recycling, and transport off island or to an approved
landfill.
Complaints procedure will be available to report any problems experienced or
observed regarding waste management during the KAIP works.

activities
Construction noise will be regularly monitored with a noise meter to ensure levels do
not exceed health and safety levels and work restricted to normal work hours (e.g.
Monday to Friday, 8am to 6pm). Any work outside normal hours will be publicised a
minimum of 24 hours prior and the method for making complaints available on signs
and through the airport.
Operational noise will be harder to combat due to the proximity of the village however
the Master Plan is being drafted at present which will look at airport operations.
Social and economic
benefits associated with the
airport operations and
construction works
Both the Social Safeguards Report, and BEIA and EMP specify the use of local
labourers where suitable and training of Government staff from other departments
which could benefit from the experience (e.g. MPWU).
Long term opportunities are harder to quantify as there are many other variables.
However improved airport facilities should benefit all in relation to passenger
experience (and return visits) and new business opportunities (e.g. concession
stands, craft stalls) but these are not the responsibility of the MCTTD.
Road upgrades so vehicles
and pedestrians do not use
the runway
Improvements to the road are outside the scope of the KAIP however this issue has
been noted by the Government.
Where applicable these concerns have been addressed either in this BEIA and EMP which is subject to further
consultation and the Social Safeguards Report. There will be another formal round of consultation regarding the
project and this BEIA and EMP (dates to be confirmed). Outcomes from future consultation will need to be
incorporated into this BEIA and EMP.
There will also be opportunity throughout the project to provide feedback and obtain information through the
complaints procedure (refer to section 8.2).
5.2.2 Consultation Summary 13 and 15 April 2013
The community meeting on the 13 April was held at KPC during a Children’s Day function and the community
meeting on 15 April was held at the Bonriki Catholic Church maneaba. The key discussion points for both these
meetings were the community facility and toilet blocks which have been proposed as a general social mitigation
measure for the general negative impacts caused by the presence of an airport beside the village (e.g. loss of
land and potential recreational facilities). Further details regarding social issues and mitigation are presented in
the Social Safeguards Report. The KAIP Task Force Committee has been responsible for undertaking
consultation and is an inter-agency committee who has led the iterative design process of the perimeter fence
location. The Bonriki community are supportive of both the TRW perimeter fence (which includes pedestrian
access gates) and the community and toilet facilities.
5.3 Disclosure
Disclosure does not equate to consultation (and vice versa) as disclosure is about transparency and
accountability through release of information about the project. The draft overarching KAIP EMP has been made
available on the WB Infoshop website and in hard copy at government offices (most applicable and accessible)
and the ECD website. A draft of this updated KAIP TRW BEIA and EMP should also be made available online
(WB and government websites) and hard copies available at government offices and community centres in South
Tarawa.
5.4 Sensitive Receptors
South Tarawa is densely populated with little available landmass for expansion and so homes and community
facilities (churches and maneaba) are located very close to the runway and airport. Homes, schools (including
pre-schools), and hospitals are categorised as sensitive receptors where people can be more susceptible to the
adverse effects of exposure, like to traffic (safety) or noise. Sensitive receptors do not usually include places of
business or public open space. Specific consultation should be undertaken with the Bonriki community before and
during construction activities to ensure impacts are minimised and community safety in ensured. This is
particularly important for the transport of materials and equipment from the port to the construction camp.
Mitigation measures may include construction works or transport during specific hours which do not impact school
hours or specific traffic (includes pedestrian) safety management like flag controls and route diversions.

6.0 Environmental and Social Impacts
6.1 Overview of Impacts
The KAIP scope is to rehabilitate the existing runway surface (including drainage) and upgrade the terminal, and
navigation aids. New land acquisition for airport operations or physical resettlement is not required and the project
is unlikely to cause any major negative environmental or social impacts as the work is improving existing
infrastructure. The social outcomes of the KAIP are expected to be positive by improving safety, accessibility and
mobility of island communities. No land acquisition is required thus no physical resettlement will be necessary. A
Social Safeguards Report has been prepared which looks specifically at the social impacts of the airport perimeter
fence and addresses the land lease dispute regarding the location of the terminal.
Possible negative impacts related to the airport are expected to be confined to the construction phase. Public
notices and consultation with affected people will continue throughout the project. Where appropriate warning
notices and project bulletins will be posted informing the community when particular stages are to be completed
and opportunities for involvement, whether through employment, collection and reuse of demolition materials or if
there are complaints. With timely and proper implementation of this EMP and application of appropriate mitigation
measures, most if not all the potential negative impacts can be prevented or minimized. These impacts are
expected to be limited to the following impacts, however this BEIA and EMP is a dynamic document and any
changes in design or construction methodology may result in a reduction of impacts or additional impacts that will
require mitigation.
6.2 Historical Development Activities and Environmental Impacts
Historical development activities at TRW have had a detrimental effect on the environment, as seen during the
site inspection tour in October 2012. Equipment such as a roller and crusher were abandoned in Bonriki village
and left to deteriorate (refer to Figure 13). Vegetation is growing through some of the machinery indicating the
length of time the equipment has been insitu. Abandoned equipment can leach contaminants from any remaining
fuel and oil and also from the material itself (e.g. heavy metals and chemicals from the paint).
Figure 12 Abandoned equipment in Bonriki village
On the north eastern side of the runway is a bitumen dump, understood to be left from the last airport works
(1990’s). There has been a fire and the bitumen has spread over the beach to the ocean. The heat and sunshine
also melts the bitumen and causes it to spread further. The bitumen appears very thick in parts (refer to Figure
14). This area has been identified as a potential temporary lay down area for use during the pavement works. This
area will require remediation by the contractor prior to use. The bitumen will need to be dug out for disposal or
recycling off island.

The World Bank operational policies and Kiribati legislation provide mechanisms and tools for preventing
environmental damage and ongoing impacts as a result of development activities. This BEIA and EMP has been
developed in accordance with these requirements (as detailed in Section 3) with the goal to ensure that impacts
such as those described above do not occur and responsibility for mitigation measures and impacts is clearly
defined.
The contractor(s) are responsible for implementation of this EMP and ensuring that all waste material and all
equipment (that cannot be reused or recycled on island) is removed at completion of the works. MCTTD is
responsible for ensuring the contractor(s) perform in accordance with their contract. This BEIA and EMP has been
included in all procurement documentation to inform contractor(s) of their responsibilities. Included in the
contractor’s contract will be a requirement to remove from island old machinery and unserviceable equipment
associated with the airport at completion of the project works.
More recently the Cassidy International Airport (CXI) runway on Kiritimati Island underwent pavement
rehabilitation works similar in scope and scale to the pavement works proposed at TRW. The TRW pavement
works component of the KAIP will be managed in a similar manner to the CXI pavement works to ensure
compliance with the site EMP, contractor’s EMP and legislative requirements.
6.3 Environmental Impacts
6.3.1 Solid Waste
Scarification, replacement of unsuitable pavement material, clearing of old terminal and derelict equipment would
lead to the generation of excess soil and debris waste. South Tarawa has recognised waste management as a
significant problem which the community and Government are struggling to overcome. Implementing reuse and
recycling opportunities are paramount as are the removal of any unusable waste (including hazardous
substances) at the end of the project. The island cannot manage the potential level of waste generated from the
demolition and construction activities and burning of waste can cause odour and health effects on the surrounding
community. Waste material or equipment which cannot be reused or recycled on island must be removed and
disposed of off island at completion of the project.
The export of waste to another territory transfers the potential solid waste impacts (e.g. air, land and water
pollution) therefore careful due diligence of the receiving waste facility is required to ensure the facility is a
licensed operation (under the receiving country’s legislation) and that it is managed according to standard
operational management practices. The trans-boundary movement of waste can also cause pollution at sea if the
waste is not properly packaged and prepared for transport.
Material will be generated from the excavations associated with navigational aids concrete pads, cable trenches,
and the apron surface and drainage rehabilitation. Most of the raw material can either be used to backfill areas
where old equipment or infrastructure has been removed or as a resource (e.g. crushed concrete) for general use
by MPWU and the community. The asphalt millings from the runway can also be used as constructed fill and will
be used to backfill behind the sea wall at the western end of the runway. Any re-use of asphalt millings must have
a paved surface to prevent asphalt dust from being mobilised and thus impacting the environment and human
health. Due to the milling process the waste product (which can also be reheated and reused in roading surfaces)

30
has high levels of polycyclic aromatic hydrocarbons (PAHs) in particulate form. Sealing the surface of any asphalt
milling fill will prevent mobilisation.
The types of waste expected to be generated are:
- Building materials from demolition
- Excess rubble generated from milling of the runway surface and excavations
- Green waste from clearing the area for the construction camp
- Packaging materials from imported supplies
- Waste oil, lubricants etc.
- Wastewater from sanitary facilities (dependent on system used).
Demolition materials, packaging, rubble and waste oil/ lubricants are traditionally taken to landfills for disposal.
South Tarawa has limited capacity at their landfills which are generally not constructed nor managed to
international standards with impermeable liners, leachate and gas collection systems and daily cover. Therefore
the impact of waste generated through the project has potential to create long term capacity and contamination
problems for the community.
6.3.2 Water Resources
Freshwater will be required for workers and some construction activities (e.g. dust suppression and concrete and
bitumen production). The impact on current water supply could be major if not properly mitigated through good
resource planning. Water efficiency, conservation and reclamation practices will be adopted, for example use of
an osmosis plant for non-potable water purification.
The demand of the terminal on Bonriki’s water supply has potential to have long term lasting impacts if not
properly addressed during the design phase.
The runway and apron provides an opportunity to harvest rainwater and replenish the freshwater lens. Additional
soakage galleries have been included in the pavement designs as has drainage on the apron to prevent flooding
of the apron and the nearby village.
6.3.3 Biological Resources
The KAIP will rehabilitate and upgrade the existing infrastructure. The southern boundary of the airport is shared
with Bonriki village which is very densely populated and developed. The northern boundary is shared with the
water reserve protection area. It is evident that even within the water reserve protection area anthropogenic
changes have already occurred. It is not anticipated that there will be any further loss of habitat or disturbance
that is not short term (e.g. related to the construction phase). There is the possibility that in the process of
construction works fauna (e.g. nesting birds) could be impacted or the temporary removal of vegetation (e.g. for
trenching or the construction camp) could impact on potential habitats. The habitats surrounding the runway are
primarily open grass with foot traffic and adhoc roads in the area. Mitigation measures will include liaison with the
ECD should any fauna (reptile, avian, or mammal) are encountered that affect construction activities (e.g. nesting
bird).
6.3.4 Hazardous Substances and Materials
Potential soil and surface water pollution from construction run-off with fuel and lubricants are expected to be
temporary and minor, provided best practice methods are implemented by the construction contractor. Work
practices and mitigation measures for spills will be implemented, including spill response plan and bunded areas
for storage (during construction and operation phase).
There is also potential for hazardous materials to be in the building materials used in existing structures that are to
be demolished (e.g. asbestos downpipes and guttering on the terminal).
There is potential for subsurface hydrocarbon impact in the vicinity of the old fuel hydrant pipes and aboveground
storage tanks (AST). Excavation or disturbance of this material could mobilise contaminants and have a potential
effect on human health (such as inhalation or dermal) and the environment ( soil and groundwater). The
excavation and exposure of the pipes also poses an explosive risk if vapours and product has built up within the
pipe and tank system.

Assessment - Bonriki International Airport (TRW) Final Draft

31
The primary risks of hydrocarbon contamination as a result of airport operations and or construction activities
relate to vapours and proximity of residential settlements and contamination of the freshwater lens. Due to the
limited level of treatment of water extracted from the freshwater lens and the use of local bores to access the
freshwater lens any groundwater hydrocarbon contamination would likely affect a number of people depending on
the length of time product has been entering the environment and in what volume. The only way to establish
potential hydrocarbon contamination is sampling of insitu soils suspected of contamination (see Section 7.2) and
or sampling and analysis of groundwater from local bores in the vicinity of the apron and above ground fuel tanks
(refer Section 7.4).
6.3.4.1 General Information on Hydrocarbon Contamination
The presence and extent of hydrocarbon contamination at TRW is unconfirmed and unquantified as the risk of
encountering it during construction activities are low due to implementation of best practice mitigation measures
as detailed in Section 7.2 and construction methodology as described in Section 2.0. The following information
relates to the type of fuel used at the TRW and the known properties and impacts of contamination generally.
Hydrocarbon contamination has a detrimental effect on aquatic life, water quality and soil quality. There are also
human health impacts regarding hydrocarbon exposure which vary in severity depending on type and length of
exposure. The onset of symptoms may not be immediate, particularly in relation to the carcinogenic compounds.
Human exposure pathways include respiration, dermal contact, and ingestion (likely through contaminated
drinking water). With the Jet A1 fuel the most likely exposure pathway is dermal contact due to the low vapour
pressure3.
If hydrocarbon product (likely Jet A1 as this is the product used most frequently and in large volumes) is spilt or
leaks from the pipe or tank system, the hydrocarbons will exist in the subsurface as free product (light, non-
aquious phase liquid – LNAPL), dissolved in groundwater and/or as vapour. Middle range distillate group of
hydrocarbons (which includes diesel, kerosene and jet fuel) tend to be a heavier hydrocarbon fraction, be less
volatile, less water soluble, and less mobile than the compounds in the petrol/gasoline hydrocarbon fraction
range. The middle distillates also contain less of the lighter-end aromatics such as BTEX (benzene, toluene,
ethylbenzene, and xylenes). Soils impacted by diesel fuel are not expected to contain high proportions of
aromatics such as BTEX. Typically, with older releases, BTEX constituents will have degraded or dispersed to
leave very low, or possibly undetectable concentrations4. Naturally occurring biodegradation (by bacteria and
fungi) occurs best under aerobic conditions provided sufficient nutrients are present for conversion of the
hydrocarbons to microbial biomass.
The range of effects in marine organisms for soluble aromatic hydrocarbons (which are comparatively more toxic
in comparison to other hydrocarbon compounds) are, in order of increasing hydrocarbon concentration3:
- Bioaccumulation may occur
- Behavioural pattern changes
- Growth and reproduction changes
- Lethal to larval and juvenile stages
- Lethal to adults
6.3.5 Noise and Vibration
Noise and vibration disturbances are particularly likely during construction related to the transportation of
construction materials from the port and operation of equipment (e.g. milling of pavement surface). These impacts
will be short-term and affect different people at different times. Impacts include noise during pavement resurfacing
and possible effect of vibration caused by operation of heavy machinery, increased traffic in some sections of
roads, etc. Due to the land constraints on South Tarawa residential houses and businesses are located in close
proximity to the airport and directly adjacent to the road network. In some areas of the road network there is little
distance from the road edge and a house or building. Therefore noise and vibration is likely to be an ongoing
issue throughout the construction stage and to a lesser degree the operational phase (e.g. aircraft landing and

take-off). As the airport is existing infrastructure any noise or vibration impacts are probably already being
experienced by the local community.
At the operational phase of the project local residents have expressed concern regarding noise from aircraft. The
scope of work for the KAIP is general maintenance and improvement with a view to ensuring the continued
operation of the airport, not increasing capacity and frequency of flights or vehicle traffic. So there will be no
increase in noise or vibration levels during operation and only potentially small decreases due to improved
pavement surfaces.
6.3.6 Erosion and Sediment Control
Some soil erosion may occur as a result of the removal of shrubs and earth cover during resurfacing, and
restoration of pavement areas and drainage. The impacts on vegetative cover will be short-term and reversible
through natural regeneration. There is only a thin topsoil layer in most parts and runoff is easily filtered into the
underlying groundwater table. Where topsoil is required to be cleared this will be set aside for use in restoration of
disturbed areas.
Sediment has the potential to be generated during any excavations or land clearing activities, particularly for
navigational aids and within the construction camp (estimated area is 1 ha). Excavation will also be required for
the terminal however details of these excavations have yet to be defined. Likely excavation requirements will be
for rainwater harvesting and installation of septic tank system and associated pipework.
6.3.7 Air Emissions
Air pollution can arise due to improper maintenance of equipment, dust generation (from excavations and
pavement milling), bitumen smoke / fumes arising from application of the new pavement seal and maintenance
work, and emissions from the asphalt plant to be located in the construction camp. Impacts are expected to be
localised and short term with only minor negative impact on the ambient air quality in the vicinity of the
construction areas. No ongoing impact to air quality is expected as this is rehabilitation of existing infrastructure.
As stated in section 6.2.5 South Tarawa is densely populated, while air quality impacts are likely to be short term
they will affect more people.
6.3.8 Traffic and Airport Operations
Traffic impacts will occur in transporting equipment and materials from the port and to and from the airport and
construction camp. These impacts will mostly be short-term and through good mitigation and traffic management
the impacts should be low. The Contractor is responsible for developing and implementing a Traffic Management
Plan (TMP). The TMP will need to consider pedestrian traffic as well as vehicle traffic management, and particular
attention will need to be given to management near sensitive receptors (residential dwellings, markets, churches
etc). Upon completion of the construction phase of works traffic and road safety impacts caused by the KAIP
should cease.
The MOWP will specify safety measures required for the operation of the airport when construction work is
underway. The MOWP includes instruction on airfield operational distances, FOD protection, airfield security, and
responsibility hierarchy and communication methods.
Effects of light pollution have been raised in previous discussions with the ECD. Upgrading the airfield lighting for
night time operations is not included in the scope of the PAIP. The PAPI approach lighting system is included in
upgrade works however this lighting is located at ground level and is only activated on aircraft approach for
landing. As there are no scheduled night time flights the PAPI will only be activated at night time if there is an
emergency landing required.
6.3.9 Wastewater Discharges
Sanitary facilities for workers will be provided to prevent lagoons or other areas being used. The terminal will have
a new septic systems installed which will require the sludge to be cleaned out periodically (dependent on level of
use).
Uncontrolled wastewater (e.g. sewage, grey water, wash water) discharges have the potential to contaminate soil,
water and spread disease. Wash water from equipment can be contaminated with hydrocarbons (e.g. oil and fuel)
which have a detrimental effect on aquatic life, water quality and soil quality. There are also human health impacts
regarding hydrocarbon exposure which vary in severity depending on type and length of exposure. Wash water
from concrete processing and cutting is highly alkaline and can burn vegetation, result in fish kills and also cause
burns to the skin. Sediment loads in wash water if allowed to discharge to either marine or freshwater systems

33
can also adversely impact aquatic life and water quality. While the potential impacts of uncontrolled discharges of
wastewater can adversely affect the receiving environment, they can be easily mitigated through planning and
implementation of mitigation measures (as outlined in Section 7.8).
6.3.10 Biosecurity
All aggregate material and equipment will most likely need to be imported as there are very limited natural
resources available on Tarawa. Imported aggregate and equipment can harbour plant and animal species which
may pose a threat to Kiribati’s biodiversity and ecosystems. The aggregate can also be a source of contamination
from pesticides and other harmful substances which can pose short and long term environmental and public
health risks.
6.3.11 Secondary and Cumulative Impacts
Secondary and cumulative impacts tend to be triggered by impacts to environmental resources that function as
integral parts of a larger system over time and space, and can initially be ‘invisible’ to the normal present time
impact assessment. Secondary impacts can include land use changes due to improved accessibility which in turn
can impact habitats and pressure on existing resources and utilities (e.g. water supply). Secondary and
cumulative impacts also often cannot be managed solely by the project executors (MCTTD). Town planning (e.g.
restricting development and clearing of land) and conservation are two examples of external influences which can
assist in reducing secondary and cumulative impacts.
Secondary and cumulative impacts are not always negative, positive impacts include increased business and
supply chain opportunities due to improved infrastructure and accessibility, improved access to health and
education facilities and employment (beyond the scope of the project).
The airport is existing infrastructure which has existing impacts (e.g. noise and dust generation). In most cases
the KAIP will not be able to remedy these impacts however the designs can lessen and in some cases mitigate
some of the impacts. For example the increase of impermeable surface without appropriate drainage has caused
localised flooding which can be mitigated through the design of improved drainage.
6.3.12 Coastal and Marine Environment Impacts
A number of activities have the potential to adversely affect the marine and coastal environment, including
uncontrolled discharges (e.g. stormwater, wastewater, spills), use of heavy machinery adjacent to the coast, and
increased shipping. Impacts range from destruction of habitat and natural protection (e.g. the boulder bank and
mangrove forest), to reduced or contaminated water quality and loss of aquatic life due to pollution.
6.4 Social Impacts
A Social Safeguards Report has been prepared to specifically address the social impacts of the perimeter fence
and land lease arrangements for the terminal. Details of the impacts and mitigation measures are provided in the
Social Safeguards Report.
6.4.1 Health and Safety
During construction and operation health and safety is to be managed through a Site Specific Safety Management
Plan (to be developed by the contractors for their respective works) and application of international environmental
and health and safety (EHS) standards. The primary hazards identified are construction on an active runway,
construction works involving hot bituminous products (up to 165 °C), and working in extreme ambient
temperatures.
If the trench required for the navigation aids cabling is to be dug to a depth greater than 1.5 m the sides of the
trench will need either batter slopes or shoring to prevent collapse. Exposed trenches pose a risk to the
community and airport operations therefore trenches will be progressively filled as the cable ducts are laid. At any
one time the maximum length of exposed trench shall be 30 m. Exposed trenches shall be secured at night to
prevent access by non-authorised personnel.

7.0 Mitigation Measures
Due to the nature of the rehabilitation activities proposed there are some mitigation measures which are
applicable to all aspects of the project, while others that are specific to particular components e.g. the terminal.
Sensitive receptors and environmental values have been identified around the airport site which will require
specific mitigation measures for safety and environmental protection. The mitigation measures are outlined in
Appendix B. The mitigation tables detail the impact or issue, the mitigation required, where this is to occur, when
this mitigation is to be applied, estimated costs, implementation responsibility and supervision responsibility.
This BEIA and EMP should be included in all bidding documents and form the basis of the Contractors EMP
which will detail implementation of the mitigation measures identified in this EMP. The EMPs are dynamic
documents which should be updated to include any variation from the current scope or addition of newly identified
impacts and mitigation measures that may arise through the bidding and contracting process (if not addressed in
the Contractor’s EMP) or consultation. The mitigation measures associated with the impacts identified above are
detailed below.
7.1 Aggregate, Materials and Equipment Importation
All materials and equipment must be fumigated and official certificates issued prior to arrival in Tarawa to ensure
no plant or animal pests are accidently introduced. The aggregate and any other fill type material will need to be
completely inert and free of contaminants. Verification of source and or results from laboratory testing must be
provided for importation. Importation permits and Quarantine certification shall be obtained from the Ministry of
Public Works and Utilities and Quarantine Department before applying for export permits from the source country
of materials. Natural resources of important biodiversity value such as coral reefs shall not be imported as
construction materials.
The increased shipping needs for the import of materials and equipment can have an adverse impact on the port
facilities and local lagoon habitats. The scale of shipping needs is to be determined by the contractor and is
dependent on the project schedule and construction methodology.
Stockpiles of aggregate and other materials (e.g. sand and topsoil) are to occur within the construction camp only.
Small (less than 2m high) temporary stockpiles are permitted adjacent to work sites with approval by MCTTD and
ECD. All stockpiles are to be managed in accordance with measures detailed in Sections 7.4, 7.7 and 7.10, and
Appendix B with site specific management requirements detailed in the contractor’s EMP.
7.2 Hazardous Substance Use, Storage and Disposal
Hazardous liquids (e.g. fuel and lubricants) must be managed within hardstand and bunded areas to prevent
runoff to surrounding permeable ground. Bunded areas (secondary containment) must contain the larger of 110
percent of the largest tank or 25 percent of the combined volumes in areas with a total storage volume equal or
greater than 1,000 liters. Bunded areas are to be impervious (water tight), constructed from chemically resistant
material, and be sheltered from the rain as rain water allowed to collect within the bund could be contaminated if
there is any hazardous substance residue on storage containers or spilt product within the bund. A spill response
plan must be in place and all workers trained in correct implementation of the spill response plan. Spill kits should
be available in close proximity to where hazardous substances are used and stored e.g. on the work truck or
beside the fuel store.
It is particularly important that care be taken when hazardous substances are used near the identified sensitive
receptors (refer Section 5.4). Consultation should be undertaken with residents to ensure hours of work are
known and the procedure for complaints is readily available on signage.
The bitumen and asphalt plant should be located at the construction camp to contain potential environmental
impacts. The location of the construction camp should be such that residential settlements are not impacted by
dust, noise or runoff.
Asbestos (hazardous substance) is suspected in some building materials used in the terminal. Other areas, such
as wrapped pipes, may also have asbestos containing material (ACM). The International Finance Corporation
(IFC) Environmental, Health and Safety (EHS) Guidelines for Occupational Health and Safety (section 2.4
Chemical Hazards) should be followed for demolition, handling and transport of any ACM. An asbestos
management plan which clearly identifies the locations where the ACM is present, its condition (e.g. whether it is
in friable form with the potential to release fibres), procedures for monitoring its condition, procedures to access

35
the locations where ACM is present to avoid damage, and training of staff who can potentially come into contact
with the material to avoid damage and prevent exposure. The plan should be made available to all persons
involved in operations and maintenance activities, including the ECD. Repair or removal and disposal of existing
ACM in buildings should only be performed by specially trained personnel (equivalent to training standards
required under applicable regulations in the United States and Europe) following Kiribati national requirements, or
in their absence, internationally recognised procedures.
The ACM will need to be removed from island so any international transport and disposal requirements will also
need to be complied with (e.g. Waigani Convention and Basel Convention) and clearly documented in the
asbestos management plan. Any personnel in contact with the ACM must be wearing suitable PPE, including
respiratory protection, suitable for the removal of asbestos to be worn while handling and transporting the
material. All workers should be provided with onsite washing facilities, and should wash hands, face, and
boots/shoes before eating, drinking or smoking, and before returning home. Work clothing should be removed as
soon as possible after arriving home and should be washed separately from other family laundry. It advisable to
have an officer from ECD and or National Health Department onsite during asbestos removal and packing to
assist in monitoring and ensuring compliance with environmental, and health and safety requirements. The exact
nature of required environmental, and health and safety requirements (also dependent on the type, scale, and
deterioration of asbestos containing material identified) should be documented in the asbestos management plan.
The plan should describe the work in detail and may include but not be limited to the following:
- Containment of interior areas where removal will occur in a negative pressure enclosure;
- Protection of walls, floors, and other surfaces with plastic sheeting;
- Construction of decontamination facilities for workers and equipment;
- Removing the ACM using wet methods, and promptly placing the material in impermeable containers;
- Final clean-up with special vacuums and dismantling of the enclosure and decontamination facilities;
- Inspection and air monitoring as the work progresses, as well as final air sampling for clearance, by an entity
independent of the contractor removing the ACM.
Hydrocarbon product and contamination has the potential to be encountered during work on the fuel hydrant
system. The process for sealing these pipes will require the pipeline to be flushed with high pressure water
(saltwater can be used) to remove any product residue. It is essential that this water is collected and treated
through an oil water separator prior to discharge. It is recommended that the treated wash water be discharged to
land outside the water reserve catchment area. During all operations involving the pipeline and associated tanks,
the area should be cordoned off and no smoking or open flame allowed within at least 10 metres.
A photoionization detector (PID) to monitor the worker breathing zone for parts per million (ppm) concentrations of
volatile organic compounds (VOCs) should be used to quantify the potential risk to workers. If the breathing zone
concentration exceeds 5 ppm, workers should move to an upwind location until vapours clear.
A combustible gas indicator (CGI) should also be available to monitor the lower explosive limits of the area around
the pipe and discharge location. If the lower explosive limit exceeds 10%, work should cease and workers should
move to an upwind location until vapours clear. Combined PID and CGI instruments are also available and are
acceptable. If any staining of the soil is observed or odour experienced a sample of the affected soil material
should be collected and measured using the PID. If the PID returns readings greater than 10 ppm the material
should be treated as contaminated fill. Depending on the volume of material it may be appropriate to excavate the
affected soils and prepare for transport off island to a facility licensed to accept hazardous waste.
The apron area will be sealed with a minimum 50 mm thick pavement (maximum 120 mm) which will prevent
ingress of water. Sealing a potentially contaminated area of soil will reduce the risk of migration of the
contaminants as water will not be able to permeate through to the area. There is still a risk from groundwater
mobilising contaminants that may be present if the groundwater level is high enough to interact with the
contaminated soil. An ECD pollution/ contamination officer should be notified when the hydrant work is to
commence to allow for monitoring and external validation of procedure for managing any contamination that may
be encountered. In the absence of any national contaminated land management requirements the IFC EHS
Guidelines should be applied, specifically Section 1.8 Contaminated Land and Section 4.1 Construction and
Decommissioning, Contaminated Land.
The new drainage system for the apron will include two fuel spill interceptors to treat runoff from the apron area.
The apron is where refuelling of aircraft occurs and aircraft park thus posing the greatest risks for hydrocarbon

contamination as a result of leaks and spills. The fuel spill interceptors require ongoing maintenance to remove
hydrocarbon product and other contaminates from the collection chambers (sludge and oil traps). The
manufacturer will provide information on cleaning regimes based on inflow however as a guide the interceptors
should be inspected after significant rain storms and or a spill has occurred. The interceptors are a secondary
mitigation measure and do not replace the implementation of emergency spill response procedures and use of
spill kits.
7.3 Safety and Traffic Management
A road runs parallel to the runway on the southern side which at it closest is approximately 25m from the edge of
the runway. There are roads at both ends of the runway that follow the ocean and lagoon coast. It was observed
that the runway is also used by private vehicles as the pavement surface is better than the adjacent road.
Therefore the construction of the perimeter fence is to take place prior to the runway resurfacing component to
restrict private vehicle use of the runway to ensure safety of the workers, aircraft and also of vehicle drivers and
passengers. Pedestrian and vehicle safety will also be an issue when transporting materials and equipment from
the port and to and from the airport site and the construction camp. The Contractors are responsible for
developing a TMP which will specify how traffic (vehicle and pedestrian) will be managed, including transport
times (outside peak hours), maximum speed and loads of trucks, use of flag controls at site entrances
(construction camp) and around specific work areas.
The MOWP will detail the specific safety and security requirements for the airport operations, including safe
operating distances and responsibility of key project roles.
7.4 Stormwater and Water Management
Available land on South Tarawa is limited and houses are located close together and close to the road and
runway edges. Localised flooding occurs on shoulders where compaction has occurred and drains have blocked.
The runway apron is being designed with new drains suitable for aircraft traffic and the type of rain events
experienced in Tarawa and include oil interceptors for capture of hydrocarbons. Stormwater soakage pits will
allow stormwater to percolate to the underlying groundwater.
During construction clean water diversion bunds will be used to direct any runoff from undisturbed areas away
from work areas, stockpiles and storage areas. The diversion bunds will direct this clean water to land for
soakage. Runoff will not be directed to discharge directly to the lagoon or ocean (other than natural overland
flow).
Water required for construction activities such as dust suppression and concrete production will need to be
managed carefully so as not to impact on the island’s freshwater supply. Water for use during construction should
be carefully planned for at the pre-construction mobilisation stage by the contractor. If required rain water should
be collected in advance and a project specific mobile desalination plant imported (or other mobile water treatment
unit). Possible non-potable water sources (e.g. seawater) and uses should be identified (e.g. dust suppression,
machinery washing), provided there will be no risk of contamination of groundwater. Water saving measures
include sweeping of work areas and vehicles tires instead of washing to prevent dust.
Due to the proximity of the water reserve protection area monitoring of selected bores should be completed prior
to construction works commence, during construction works and at completion of all construction works.
Depending on what works are being undertaken (e.g. terminal versus runway pavement) different bores may be
selected to provide information on groundwater quality at any given time in that area. As a minimum the bores that
should be included in the monitoring programme are the terminal bore, to capture activities related to the terminal
upgrade and apron pavement works, and the bores located adjacent to the runway (e.g. BN5 and BN14, refer to
Figure 10 in Sect5ion 4.1.4), to capture any potential effects of the runway pavement rehabilitation. Other bores
may also be identified by the ECD as requiring monitoring to determine effects from construction and or
operational activities.
Parameters that should be monitored include pH, electrical conductivity and total petroleum hydrocarbons (TPH).
Runoff from disturbed areas is not to be discharged directly to the marine or coastal environment. Sediment laden
runoff is to be treated (via small settling pond or tank) and discharged to land (outside the water reserve
protection area) or reused.

7.5 Bitumen, Asphalt and Concrete Plant
Bitumen and asphalt production requires very high temperatures which pose a significant risk to workers and the
general public. Therefore the bitumen and asphalt plant should be located within a secure compound (the
construction camp) to ensure security and reduce risk of unauthorised access. The plant also requires use of
hazardous materials which must be stored on hard stand areas within bunded areas (both should be available at
the construction camp). The equipment must be fitted with a dust scrubber to prevent the dispersal of fine coral
particulates. The pavement asphalt should not be applied during wet weather to reduce the possible leaching of
contaminants from the bitumen.
The project requires concrete production for the terminal, navigational aids and the perimeter fence. It is unknown
whether the bulk of concrete will be prefabricated off island, at a concrete plant on the island or in-situ. If concrete
is to be constructed on the island care needs to be taken with slurry and runoff from the concrete. Concrete
production should only take place when there is no rain forecast and not within the coastal margin (e.g. restricted
to the construction camp). Concrete slurry is highly alkali and cannot be diluted. Sand bags or diversion drains
must be used to divert runoff from concrete cutting or setting areas. Any concrete debris must be collected and
disposed of as a hazardous substance and removed from the island. Wastewater from concrete cutting or
production must be collected and treated (settling and neutralisation through pH adjustment). All equipment used
in concrete production must be cleaned in designated wash down areas away from surface water and not be
allowed to permeate to ground.
7.6 Construction Camp
The construction camp will be used to store equipment and materials for all components of the project, and as
such there are a number of potential hazards associated with the equipment and materials. The construction
camp compound must be fenced and secured to prevent access by unauthorised personal. Areas within the
compound must be clearly marked for solid waste collection, machinery maintenance, hazardous substance
storage, plant operations (concrete, bitumen, asphalt) and toilet facilities for workers. Each of these areas must be
constructed in such a way to prevent any potential adverse impacts on the surrounding environment. Including
hard stand areas, protection from wind and rain, bunding (hazardous substances), clean water diversion drains,
and collection and treatment of waste water from site operations (e.g. concrete production, machinery
maintenance). The construction camp is not a residential camp. Foreign contract and project staff will utilise
existing local accommodation. The ground of the construction camp will likely by compacted by the end of its use
and so restoration will require scarification of the soil, application of topsoil and revegetation.
7.7 Erosion and Sediment Control
The land on Tarawa is relatively flat, low lying with porous soils. Wet weather is usually experienced as short,
heavy rainfall events, often in the morning or at night. Clean water diversion bunds should be constructed around
any excavation to prevent ingress of runoff from surrounding areas. Any ponding which may occur within an
excavated area shall either be allowed to percolate into the subsoil or pumped out to a settling area or used for
dust suppression at a later date. Excavations should be kept to a manageable size to reduce the time of
exposure. The largest stockpiles will be within the construction camp for the imported aggregate. These stockpiles
will need to be on an impermeable geotextile or hardstand and runoff directed to permeable land. The aggregate
material will be inert larger size pieces. Stockpiles of any fine grain materials (e.g. sand and topsoil) must be
covered to prevent dust and sediment laden runoff during rain events.
The eastern runway end is approximately 85 m from the lagoon foreshore and less than 20 m (at the nearest
point) from the ocean beach (western end). Discharges from any construction activity at the these locations are
prohibited from discharging directly to the marine and coastal environment. Clean runoff should be diverted inland
for percolation to underlying groundwater, and potentially contaminated runoff should be collected and treated.
Treatment will be dependent on type of potential contamination (e.g. oil water separator for runoff contaminated
with hydrocarbons, or settling pond or tank for sediment laden runoff).
7.8 Wastewater Management
There are a number of activities during construction and operation phases of the project which will generate
wastewater. During construction wastewater will be generated by the sanitation facilities provided for workers and
as there is no reticulated wastewater treatment system for this area of the island, the contractor is responsible for
the collection and treatment of the generated wastewater from sanitation facilities. There are a number of options

regarding sewage treatment that the contractor can implement to mitigate the potential impacts on the land and or
water (ocean or groundwater). These include mobile proprietary treatment systems (to be imported for the project)
and composting systems. The contractor is responsible for ensuring the treatment and disposal of wastewater is
in accordance with MCTTD, MPWU and ECD advice and approved by MCTTD and MPWU.
Wastewater from wash down areas is to be collected either in a settlement pond or tank to allow sediment and
particulate matter to drop out before the water can be reused as wash water, dust suppression or in other
processes. A separate wash down area is required for machinery or material with oil or fuel residue as this wash
water is required to be treated through a mobile oil water separator. Wash water from concrete production,
cutting, washing of equipment used and areas where concrete is produced must be collected and treated to lower
the pH (closer to neutral) and to allow settlement of suspended solids (see Section 7.5). All wash down areas and
wastewater treatment areas, where practical should be located within the construction camp or lay down areas.
Treated wash water where possible should be reused for dust suppression or within other processes. Direct
discharge to the marine or coastal environment is prohibited. Discharges of treated wash water are to occur to
land only (outside the water reserve catchment area). Sufficient measures to avoid direct discharges are required
when working adjacent to the marine and coastal environment, particularly for the runway resurfacing component,
which may include bunding (e.g. sand bags), demarcation of exclusion zones, and limited use of large machinery.
7.9 Solid Waste Management
Waste generated by the project that cannot be recycled or reused (to be determined in consultation with the
MCTTD, MPWU, ECD and Teinainano Urban Council) is to be removed from Kiribati at the completion of the
contractors work. The contractor is responsible for ensuring the waste is packed in shipping containers or other
suitable impermeable containment to ensure waste (solid and liquid) is not inadvertently discharged at sea.
Details of the receiving waste facility (including transport documentation and agreements to receive the waste)
must be provided to MCTTD to ensure the facility is licensed or permitted.
General waste (including plastics and packaging) is not to be burnt or incinerated. Vegetative waste (from clearing
construction areas) should be composted through existing composting schemes (contact the Teinainano Urban
Council and or ECD) and topsoil stockpiled for rehabilitation of the construction camp and or lay down areas at
completion of the project. If burning or incineration of vegetation is the only suitable disposal method and agreed
to by MCTTD, ECD and the Teinainano Urban Council then it shall be undertaken with supervision by the onsite
Supervising Engineer and in accordance with local legislation and regulations. Burning or incineration is not to
occur near any residential or community facilities, areas of protected vegetation or during high winds.
Excess pavement/asphalt millings that cannot be reused within the project will be made available to MCTTD and
MPWU for use as constructed fill or reheated and reused (if material is suitable). Use of the asphalt millings as fill
will require sealing with a paved surface to prevent the mobilisation of asphalt dust. Stockpiles of asphalt millings
must be located within the construction camp on an impermeable surface and managed to prevent dust. If the
material is to remain on island as a construction material resource MCTTD and or MPWU will take responsibility
and manage the material in accordance with this EMP and under guidance from the ECD.
7.10 Marine and Coastal Specific Mitigation Measures
The runway runs in an east to west direction with the lagoon at the western end (approximately 90m from the end
of the runway) and the ocean at the eastern end (less than 20m at the closest point). All project work for the
runway will be occurring inland and there will be no direct or indirect discharges (stormwater or wastewater) to the
marine environment. The ends of the runway are in close proximity to the coast as is a potential lay down area.
Therefore work in these areas will need to manage runoff by directing it inland from the beach and marine
environment. Heavy machinery operating adjacent to the beach should stay on the existing pavement or inland
and not venture on the beach or seawall. Temporary stockpiles and equipment parking is prohibited on the beach.

8.0 Roles and Responsibilities
The MCTTD is responsible for delivery of the KAIP project (including all components), funding received and
contracts awarded under the KAIP. MCTTD is the Implementing Agency in regards to funding received from
donors including the WB. A Project Management Unit (PMU) within MCTTD has been established to undertake
the day to day management of the project. Aspects of the monitoring required by the EMP will be undertaken by
MCTTD. The implementation of this EMP is the responsibility of the contractors awarded contracts under the
KAIP. The diagram below shows the reporting and responsibilities for this EMP. The ECD has a statutory
responsibility to respond to pollution complaints, and ensuring impacts are managed as per the EMP. There will
also be ongoing airport operational monitoring requirements of the ECD. The Department of Public Works will
work alongside the Resident Engineer in order to capacity build within the department and for ongoing
maintenance of the runway repairs.
8.1 Institutional Capacity
MCTTD will require environmental awareness training for monitoring the Contractors. Personnel from the MPWU
will work alongside the Contractor and Resident Engineer to capacity build and gain a better understanding of the
type of runway surface seal being used and ongoing maintenance requirements. A training budget must be put
aside to enable this capacity building with the Government departments. There may also be an opportunity for an
Officer from the ECD to work with the Contractor’s environmental officer. X-ray equipment for security screening
has been recommended however this may not be implemented as part of the KAIP. Costs for ongoing monitoring
of x-ray equipment have been included below but are provisional based on whether x-ray equipment is actually
installed. It is understood that noise meters will be required.
An indicative training budget is as follows:
Training for Contractors and CAD/ MPWU personnel (onsite training in Kiribati) US$ 15,000
Operational monitoring of x-ray equipment (annual cost) US$ 1,000
Procurement of two noise meters for monitoring (plus duty and delivery) US$ 1,000
Miscellaneous (e.g. ECD participation) US$ 2,000
TOTAL Budget US$ 18,500
8.2 Complaints and Incident Reporting
All complaints and incidents should be referred to the Supervision Consultant’s Project Officer (or designated
staff) for undertaking complaint/incident investigation procedures. All complaints must be acknowledged with the
complainant within 24hours. In general the following procedure should be followed:
- Log complaint/incident, date of receipt and acknowledge complaint receipt
- Investigate the complaint/incident to determine its validity and to assess the source of the problem

9.0 Compliance and Monitoring Plan
9.1 Monitoring Plan
The Environmental Monitoring Plan identifies the environmental monitoring requirements to ensure that all the
mitigation measures identified in this EMP are implemented effectively. Environmental monitoring methodology
(refer Appendix C for details) for this project includes:
- Audit of detailed designs.
- Audit and approval of site environmental planning documents.
- Consultations with communities and other stakeholders as required.
- Routine site inspection of construction works to confirm or otherwise the implementation and effectiveness of
required environmental mitigation measures.
Non-compliance of implementation of environmental mitigation measures identified in the EMP will be advised to
the Contractor(s) in writing by MCTTD’s nominated Environmental Officer as required. The non-compliance
notification will identify the problem, including the actions the Contractor needs to take and a time frame for
implementing the corrective action.
9.2 Monitoring Plan Reporting
Throughout the construction period, the Contractor(s) will include results of the EMP monitoring in a monthly
report for submission to the MCTTD who is responsible for submitting these monthly progress reports to the PAIP
Technical and Fiduciary Services Unit (TFSU). The format of the monthly report shall be agreed with all agencies
but is recommended to include the following aspects:
- Description and results of environmental monitoring activities undertaken during the month.
- Status of implementation of relevant environmental mitigation measures pertaining to the works.
- Key environmental problems encountered and actions taken to rectify problems.
- Summary of non-compliance notifications issued to the Contractor during the month.
- Summary of environmental complaints received and actions taken.
- Key environmental issues to be addressed in the coming month.
A day to day contract diary is to be maintained pertaining to administration of the contract, request forms and
orders given to the Contractor(s), and any other information which may at a later date be of assistance in
resolving queries which may arise concerning execution of works. This day to day contract diary is to include any
environmental events that may arise in the course of the day, including incidents and response, complaints and
inspections completed.
During airport operations the TRW Managers will include an environmental management section as part of their
normal reporting the MCTTD. The environmental management section shall include an analysis of the operation
monitoring programme, any environmental issues arising and recommendations (including cost estimates as
required) for further action.
MCTTD is also responsible for project quarterly progress reports to the WB. This quarterly progress report will
include a section on environmental compliance and issues. This section will cover (as a minimum) the overall
compliance with implementation of the EMP, any environmental issues arising as a result of project works and
how these issues will be remedied or mitigated, and the schedule for completion of project works.

10.0 Contingency Plan
It is recommended that the Contractor(s) prepare a Contingency Plan encompassing tsunami, cyclone and storm
events. The purpose of the Plan is to ensure all staff are fully aware of their responsibilities in respect to human
safety and environmental risk reduction. Procedures should clearly delineate the roles and responsibilities of staff,
define the functions to be performed by them, the process to be followed in the performance of these functions
including tools and equipment to be kept in readiness, and an emergency medical plan. All of the Contractor’s
staff should undergo training/induction to the Plan.
The wet season on Tarawa is November to April which coincides with the cyclone season. Construction activities
should be limited to the dry season (May to October) however storm and rain events can still occur during this
period causing flooding and bringing high winds.
The Contractors are responsible for monitoring weather forecasts, inspecting all erosion and sediment control
measures and undertaking any remedial works required prior to the forecast rain or storm event.
In general the Contractors will:
- Inspect daily weather patterns to anticipate periods of risk and be prepared to undertake remedial works on
erosion and sediment control measures to suit the climatic conditions;
- Monitor the effectiveness of such measures after storms and incorporate improvements where possible in
accordance with best management practice;
- Ensure appropriate resources are available to deal with the installation of additional controls as and when
needed; and
- Inform MCTTD if there are any concerns associated with the measures in place.
